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....

Rework of how xfs syncs metadata to disk. This has a number of
benefits: We no longer walk the list of all the inodes in the
filesystem everytime the write_super is called. If you type
sync and then reset the box then everything is definitely
recovered afterwards. We remove a lot of calls to
mark_inode_dirty which did not really do us any good, and
replace them with a single one which does. kupdated does
less work in xfs now, freeing it to do other things.
Finally, get the dummy log record code working, this
means that after a period of inactivity with everything
on disk, we clean the log so that recovery does not
have any work to do.

This is a two fold change, first it moves the translation
between linux dev_t and kdev_t up the call stack in xfs
and makes the bulk of xfs work in terms of its on disk
dev_t format. It also cleans up a few related chunks of
code.

The other part of the change reworks how we keep the linux
inode contents and the xfs inode fields in sync. A number
of places where we resynced the two have been removed, these
were basically replicating work elsewhere in the filesystem.
We now also ensure that the inode fields are filled in
before calling unlock_new_inode - there used to be a window.
Finally all the code which hooks together the linux inode
and the xfs inode is brought together as a more coherent
whole rather than being scattered around the inode create
path. Most calls to revalidate the linux inode from the
xfs inode are removed.
Add a new vfs operation - INIT_INODE. This is used by the filesystem
to glue the xfs inode, the vnode and the linux inode together.

To fix dm_handle_to_path() I need to be able to open a file by its handle,
when I don't know which filesystem the handle belongs to--meaning, I don't
have an open filedescriptor that I could use in, say,
ioctl(XFS_IOC_OPEN_BY_HANDLE), which means I don't have access to a vfsmount
ptr, which means I can't fully populate a new "struct file", which means
I'm giving the user a new filedescriptor that isn't safe to use.

This mod allows DMAPI to keep a vfsmount pointer that was used during the
mount event, and in a followup mod I will use that pointer for an
open_by_handle operation.
Change vfs_dmapi_mount prototype and VFSOPS_DMAPI_MOUNT macro to send
vfsmount ptr.
