Finish removing the mount pointer from the AIL API

Change all the remaining AIL API functions that are passed
struct xfs_mount pointers to pass pointers directly to the
struct xfs_ail being used. With this conversion, all external
access to the AIL is via the struct xfs_ail. Hence the operation
and referencing of the AIL is almost entirely independent of
the xfs_mount that is using it - it is now much more tightly
tied to the log and the items it is tracking in the log than
it is tied to the xfs_mount.

Given the log a pointer to the AIL

When we need to go from the log to the AIL, we have
to go via the xfs_mount. Add a xfs_ail pointer to the log
so we can go directly to the AIL associated with the log.

move the AIl traversal over to a consistent interface

With the new cursor interface, it makes sense to make all the
traversing code use the cursor interface and make the old one go
away. This means more of the AIL interfacing is done by passing
struct xfs_ail pointers around the place instead of struct
xfs_mount pointers.

We can replace the use of xfs_trans_first_ail() in
xfs_log_need_covered() as it is only checking if the AIL is empty.
We can do that with a call to xfs_trans_ail_tail() instead, where a
zero LSN returned indicates and empty AIL...

Use a cursor for AIL traversal.

To replace the current generation number ensuring sanity of the AIL
traversal, replace it with an external cursor that is linked to the
AIL.

Basically, we store the next item in the cursor whenever we want to
drop the AIL lock to do something to the current item.  When we
regain the lock. the current item may already be free, so we can't
reference it, but the next item in the traversal is already held in
the cursor.

When we move or delete an object, we search all the active cursors
and if there is an item match we clear the cursor(s) that point to
the object. This forces the traversal to restart transparently.

We don't invalidate the cursor on insert because the cursor still
points to a valid item. If the intem is inserted between the current
item and the cursor it does not matter; the traversal is considered
to be past the insertion point so it will be picked up in the next
traversal.

Hence traversal restarts pretty much disappear altogether with this
method of traversal, which should substantially reduce the overhead
of pushing on a busy AIL.

fix barrier fail detection

Currently we disable barriers as soon as we get a buffer in xlog_iodone
that has the XBF_ORDERED flag cleared.  But this can be the case not only
for buffers where the barrier failed, but also the first buffer of a
split log write in case of a log wraparound.  Due to the disabled
barriers we can easily get directory corruption on unclean shutdowns.
So instead of using this check add a new buffer flag for failed barrier
writes.

This is a regression vs 2.6.26 caused by patch to use the right macro
to check for the ORDERED flag, as we previously got true returned for
every buffer.

Thanks to Toei Rei for reporting the bug.

Fix reference counting race on log buffers

    When we release the iclog, we do an atomic_dec_and_lock to determine if
    we are the last reference and need to trigger update of log headers and
    writeout.  However, in xlog_state_get_iclog_space() we also need to
    check if we have the last reference count there.  If we do, we release
    the log buffer, otherwise we decrement the reference count.

    But the compare and decrement in xlog_state_get_iclog_space() is not
    atomic, so both places can see a reference count of 2 and neither will
    release the iclog.  That leads to a filesystem hang.

    Close the race by replacing the atomic_read() and atomic_dec() pair with
    atomic_add_unless() to ensure that they are executed atomically.

Move memory allocations for log tracing out of the critical path

Memory allocations for log->l_grant_trace and iclog->ic_trace are done
on demand when the first event is logged.  In xlog_state_get_iclog_space()
we call xlog_trace_iclog() under a spinlock and allocating memory here can
cause us to sleep with a spinlock held and deadlock the system.

For the log grant tracing we use KM_NOSLEEP but that means we can lose
trace entries.  Since there is no locking to serialize the log grant
tracing we could race and have multiple allocations and leak memory.

So move the allocations to where we initialize the log/iclog structures.
Use KM_NOFS to avoid recursing into the filesystem and drop log->l_trace
since it's not even used.

Use KM_NOFS for debug trace buffers

Use KM_NOFS to prevent recursion back into the filesystem which can
cause deadlocks.

In the case of xfs_iread() we hold the lock on the inode cluster buffer
while allocating memory for the trace buffers.  If we recurse back into
XFS to flush data that may require a transaction to allocate extents
which needs log space.  This can deadlock with the xfsaild thread which
can't push the tail of the log because it is trying to get the inode

Convert l_flushsema to a sv_t

The l_flushsema doesn't exactly have completion semantics, nor mutex
semantics.  It's used as a list of tasks which are waiting to be notified
that a flush has completed.  It was also being used in a way that was

By using a sv_t instead of a semaphore we avoid the need for a
separate counter, since we know we just need to wake everything on the
queue.

Sanitise xfs_log_force error checking.

xfs_log_force() is declared to return an error, but we almost never
check it. We don't need to check it in most cases; if there's a log
I/O error then we'll be shutting down the filesystem anyway and that
means we'll catch the error somewhere else.

However, on certain calls we should be returning an error - sync
transactions, fsync, sync writes, etc. so this isn't a pure black
and white distinction. Hence make xfs_log_force() a void function
that issues a warning to the syslog on error, and call
_xfs_log_force() in all the places where we actually care about the
error status returned.

Use atomics for iclog reference counting

Now that we update the log tail LSN less frequently on
transaction completion, we pass the contention straight to
the global log state lock (l_iclog_lock) during transaction
completion.

We currently have to take this lock to decrement the iclog
reference count. there is a reference count on each iclog,
so we need to take þhe global lock for all refcount changes.

When large numbers of processes are all doing small trnasctions,
the iclog reference counts will be quite high, and the state change
that absolutely requires the l_iclog_lock is the except rather than
the norm.

Change the reference counting on the iclogs to use atomic_inc/dec
so that we can use atomic_dec_and_lock during transaction completion
and avoid the need for grabbing the l_iclog_lock for every reference
count decrement except the one that matters - the last.

Prevent AIL lock contention during transaction completion

When hundreds of processors attempt to commit transactions at the
same time, they can contend on the AIL lock when updating the tail
LSN held in the in-core log structure.

At the moment, the tail LSN is only needed when actually writing
out an iclog, so it really does not need to be updated on every
single transaction completion - only those that result in switching
iclogs and flushing them to disk.

The result is that we reduce the number of times we need to grab the
AIL lock and the log grant lock by up to two orders of magnitude
on large processor count machines. The problem has previously been
hidden by AIL lock contention walking the AIL list which was
recently solved and uncovered this issue.

Move AIL pushing into it's own thread

When many hundreds to thousands of threads all try to do simultaneous
transactions and the log is in a tail-pushing situation (i.e. full),
we can get multiple threads walking the AIL list and contending on
the AIL lock.

The AIL push is, in effect, a simple I/O dispatch algorithm complicated
by the ordering constraints placed on it by the transaction subsystem.
It really does not need multiple threads to push on it - even when
only a single CPU is pushing the AIL, it can push the I/O out far faster
that pretty much any disk subsystem can handle.

So, to avoid contention problems stemming from multiple list walkers,
move the list walk off into another thread and simply provide a "target"
to push to. When a thread requires a push, it sets the target and wakes
the push thread, then goes to sleep waiting for the required amount
of space to become available in the log.

This mechanism should also be a lot fairer under heavy load as the
waiters will queue in arrival order, rather than queuing in "who completed
a push first" order.

Also, by moving the pushing to a separate thread we can do more effectively
overload detection and prevention as we can keep context from loop iteration
to loop iteration. That is, we can push only part of the list each loop and not
have to loop back to the start of the list every time we run. This should
also help by reducing the number of items we try to lock and/or push items
that we cannot move.

Note that this patch is not intended to solve the inefficiencies in the
AIL structure and the associated issues with extremely large list contents.
That needs to be addresses separately; parallel access would cause problems
to any new structure as well, so I'm only aiming to isolate the structure
from unbounded parallelism here.

Remove bogus assert,

lachlan says:
> This assert is bogus.  We can have a forced shutdown occur between the check for
the XLOG_FORCED_SHUTDOWN and the ASSERT.  Also, the logging system shouldn't care
about the state of XFS_FORCED_SHUTDOWN, it should only check XLOG_FORCED_SHUTDOWN.
The logging system has it's own forced shutdown flag so, for the case of a forced
shutdown that's not due to a logging error, we can flush the log.  I suggest

xlog_rec_header/xlog_rec_ext_header endianess annotations

Mostly trivial conversion with one exceptions:  h_num_logops was kept
in native endian previously and only converted to big endian in
xlog_sync, but we always keep it big endian now.  With todays cpus
fast byteswap instructions that's not an issue but the new variant
keeps the code clean and maintainable.

Lazy Superblock Counters

When we have a couple of hundred transactions on the fly at once,
they all typically modify the on disk superblock in some way.
create/unclink/mkdir/rmdir modify inode counts, allocation/freeing
modify free block counts.

When these counts are modified in a transaction, the must eventually
lock the superblock buffer and apply the mods.  The buffer then
remains locked until the transaction is committed into the incore
log buffer. The result of this is that with enough transactions on
the fly the incore superblock buffer becomes a bottleneck.

The result of contention on the incore superblock buffer is that
transaction rates fall - the more pressure that is put on the
superblock buffer, the slower things go.

The key to removing the contention is to not require the superblock
fields in question to be locked. We do that by not marking the
superblock dirty in the transaction. IOWs, we modify the incore
superblock but do not modify the cached superblock buffer. In short,
we do not log superblock modifications to critical fields in the
superblock on every transaction. In fact we only do it just before
we write the superblock to disk every sync period or just before
unmount.

This creates an interesting problem - if we don't log or write out
the fields in every transaction, then how do the values get
recovered after a crash? the answer is simple - we keep enough
duplicate, logged information in other structures that we can
reconstruct the correct count  after log recovery has been
performed.

It is the AGF and AGI structures that contain the duplicate
information; after recovery, we walk every AGI and AGF and sum their
individual counters to get the correct value, and we do a
transaction into the log to correct them. An optimisation of this is
that if we have a clean unmount record, we know the value in the
superblock is correct, so we can avoid the summation walk under
normal conditions and so mount/recovery times do not change under
normal operation.

One wrinkle that was discovered during development was that the
blocks used in the freespace btrees are never accounted for in the
AGF counters. This was once a valid optimisation to make; when the
filesystem is full, the free space btrees are empty and consume no
space. Hence when it matters, the "accounting" is correct.  But that
means the when we do the AGF summations, we would not have a correct
count and xfs_check would complain.  Hence a new counter was added
to track the number of blocks used by the free space btrees. This is
an *on-disk format change*.

As a result of this, lazy superblock counters are a mkfs option
and at the moment on linux there is no way to convert an old
filesystem. This is possible - xfs_db can be used to twiddle the
right bits and then xfs_repair will do the format conversion
for you. Similarly, you can convert backwards as well. At some point
we'll add functionality to xfs_admin to do the bit twiddling
easily....

Fix vmalloc leak on mount/unmount.

When setting the length of the iclogbuf to write out we should just
be changing the desired byte count rather completely reassociating
the buffer memory with the buffer. Reassociating the buffer memory
changes the apparent length of the buffer and hence when we free the
buffer, we don't free all the vmap()d space we originally allocated.

write barrier support

Issue all log sync operations as ordered writes.  In addition flush the
disk cache on fsync if the sync cached operation didn't sync the log to
disk (this requires some additional bookeping in the transaction and log
code).
If the device doesn't claim to support barriers, the filesystem has an
extern log volume or the trial superblock write with barriers enabled
failed we disable barriers and print a warning.  We should probably fail
the mount completely, but that could lead to nasty boot failures for
the root filesystem.

Not enabled by default yet, needs more destructive testing first.

Fix up the calculation of the reservation overhead to hopefully include
all the components which make up the transaction in the ondisk log.
Having this incomplete has shown up as problems on IRIX when some v2
log changes went in. The symptom was the msg of
"xfs_log_write: reservation ran out. Need to up reservation" and was
seen on synchronous writes on files with lots of holes
(and therefore lots of extents).

A problem was found with the debug code in xlog_state_do_callback.  At
the end of processing all log buffers that can be processed, there is
a (debug only) double-check to make sure that log buffers with
completed I/O don't get marooned when the function completes.  The
check only needs to go to the first buffer that will cause an I/O
completion, that has not completed.  The loop doesn't stop a WANT_SYNC
state buffer is found, but it should.
Add WANT_SYNC to the list of states that the xlog_state_do_callback DEBUG
check should stop at when it is encountered.

Change xlog_verify_iclog() to use idx as zero based instead
of 1 based index into array. To do this use BTOBBT() instead
of BTOBB() to work out which page (starting from zero) that
we are on. This then requires idx comparison to be altered
from > to >= (as was initially used in Glen's IRIX change).
The change is needed for extraction of the oh_clientid and oh_len fields.

fix a couple of nasty log problems. When a transaction crosses
multiple iclogs, the async transaction code needs to force the
log up until the last iclog. We need to record this lsn in the
transaction so we can do a log flush on it.
Secondly, there was a sleep/wakeup pair between flushing the
log and log write completions which was a) incorrect, and b)
no longer needed. This could result in early wakeups of
threads waiting for log flushes.
remove an sv_signal and an sv_wait on the ic_forcesema
which could lead to early wakeups.

Fixed a race between the setting of the iclog states and the switching of the
current head iclog that was causing us to bail out of xlog_state_do_callback
prematurely. This resulted in one of the iclog remaining in
XLOG_STATE_DONE_SYNC and threads being blocked due to this. Added a new
state, XLOG_STATE_DO_CALLBACK, to prevent this race. Changes are all in
xlog_state_do_callback().

This fixes a hole in the algorithm used by XFS to allocate logspace
to transactions. For transactions using a permanent log reservation
there was no queueing enforced on space reservation requests which
meant that a thread which just completed one transaction which freed
a bit of space could reuse that space before another waiting thread
could be scheduled. Under heavy load (such as AIM 7) this could
result in a thread getting starved of log reservations until one
of its transactions reached the tail of the log with an inode
locked so the tail could no longer move. By making a thread requesting
space go to the back of the queue we guarantee that everyone gets
a turn at the log and the tail keeps moving.

Rather than sleeping in xlog_state_switch_iclogs(), the flushsema semaphore
has been changed from a counting semaphore to a sleeping semaphore.  Threads
sleep in xlog_state_get_iclog_space() when the head of the iclog Q is not
in the ACTIVE state.  Syncing threads *do not* need to call psema.  In the
xlog_state_do_callback routine which performs callbacks and cleans up the
log, we now do a while(cvsema()) on the flush semaphore.

	hold off new log writers.  There is now an ordering placed on
	in-core logs.

1.  Fix iodone() complete routines to perform locking correctly.
2.  Correct some problems in the log_write() code w.r.t. the offset in the
	current in-core log.
3.  Add the notion of a start record for transactions.
4.  Every 512 byte block will have a pass number stamped in the first word
	of the block.  However, log record headers have their magic number
	in the first word with the pass number in the second word.
5. Add notion of splitting individual regions across multiple log record
	writes.

First cut at making the transaction
code use the log manager interfaces.  xfs_trans.h now
depends on xfs_log.h, so we need to include it.

Most of the log state machine works now.  The incore logs are now managed
in a ring.  As part of the state machine, the MP locks are in place for MP
operation.  More states have been added to the state machine.  A test program
can now write 2 log records and the commit record which requires reusing
an iclog.

Remove old ticket code where ticket handles were integers rather than
pointers to tickets.  Even though this exposes tickets outside the log
manager interface, it allows far fewer locks.

First cut of log manager code.  All my code is under LOG_DEBUG #ifdefs.
The current code should be able to write regions to disk.  log print
routines are also present.
