Move XFS_BMAP_SANITY_CHECK out of line.

Move the XFS_BMAP_SANITY_CHECK macro out of line and make it a properly typed
function.  Also pass the xfs_buf for the btree block instead of just the btree
block header, as we will need some additional information for it to implement
CRC checking of btree blocks.

Always use struct xfs_btree_block instead of short / longform structures.

Always use the generic xfs_btree_block type instead of the short / long
structures.  Add XFS_BTREE_SBLOCK_LEN / XFS_BTREE_LBLOCK_LEN defines for
the length of a short / long form block.  The rationale for this is that
we will grow more btree block header variants to support CRCs and other
RAS information, and always accessing them through the same datatype
with unions for the short / long form pointers makes implementing this
much easier.

cleanup btree record / key / ptr addressing macros.

Replace the generic record / key / ptr addressing macros that use cpp token
pasting with simpler macros that do the job for just one given btree type.
The new macros lose the cur argument and thus can be used outside the core
btree code, but also gain an xfs_mount * argument to allow for checking the
CRC flag in the near future.  Note that many of these macros aren't actually
used in the kernel code, but only in userspace (mostly in xfs_repair).

Cleanup maxrecs calculation.

Clean up the way the maximum and minimum records for the btree blocks are
calculated.  For the alloc and inobt btrees all the values are pre-calculated
in xfs_mount_common, and we switch the current loop around the ugly generic
macros that use cpp token pasting to generate type names to two small helpers
in normal C code.  For the bmbt and bmdr trees these helpers also exist,
but can be called during runtime, too.  Here we also kill various macros
dealing with them and inline the logic into the get_minrecs / get_maxrecs /
get_dmaxrecs methods in xfs_bmap_btree.c.

Note that all these new helpers take an xfs_mount * argument which will
be needed to determine the size of a btree block once we add support for
extended btree blocks with CRCs and other RAS information.

move xfs_bmbt_newroot to common code

xfs_bmbt_newroot is a mostly generic implementation of moving from
an inode root to a real block based root.  So move it to xfs_btree.c
where it can use all the nice infrastructure there and make it pointer
size agnostic

The new name for it is xfs_btree_new_iroot, following the old naming
but making it clear we're dealing with the root in inode case here,
and to avoid confusion with xfs_btree_new_root which is used for the
not inode rooted case.

split up xfs_btree_init_cursor

xfs_btree_init_cursor contains close to little shared code for the different
btrees and will get even more non-common code in the future.  Split it up
into one routine per btree type.

Because xfs_btree_dup_cursor needs to call the init routine for a generic
btree cursor add a new btree operation vector that contains a dup_cursor
method that initializes a new cursor based on an existing one.

The btree operations vector is based on an idea and code from Dave Chinner
and will grow more entries later during this series.

if its not already it was never really written anywhere ... just an

Prevent xfs_bmap_check_leaf_extents() from referencing unmapped memory.

While investigating the extent corruption bug I ran into this bug in
debug only code.  xfs_bmap_check_leaf_extents() loops through the leaf
blocks of the extent btree checking that every extent is entirely
before the next extent.  It also compares the last extent in the previous
block to the first extent in the current block when the previous block
has been released and potentially unmapped.  So take a copy of the last
extent instead of a pointer.  Also move the last extent check out of the
loop because we only need to do it once.

optimize XFS_IS_REALTIME_INODE w/o realtime config

Use XFS_IS_REALTIME_INODE in more places, and #define it to
0 if CONFIG_XFS_RT is off.  This should be safe because mount
checks in xfs_rtmount_init:

# define xfs_rtmount_init(m)    (((mp)->m_sb.sb_rblocks == 0)? 0 : (ENOSYS))

so if we get mounted w/o CONFIG_XFS_RT, no realtime inodes should
be encountered after that.

Defining XFS_IS_REALTIME_INODE to 0 saves a bit of stack space,
presumeably gcc can optimize around the various "if (0)" type
checks:

xfs_alloc_file_space    -8
xfs_bmap_adjacent       -16
xfs_bmapi               -8

Concurrent Multi-File Data Streams

In media spaces, video is often stored in a frame-per-file format.
When dealing with uncompressed realtime HD video streams in this format,
it is crucial that files do not get fragmented and that multiple files
a placed contiguously on disk.

When multiple streams are being ingested and played out at the same
time, it is critical that the filesystem does not cross the streams
and interleave them together as this creates seek and readahead
cache miss latency and prevents both ingest and playout from meeting
frame rate targets.

This patch set creates a "stream of files" concept into the allocator
to place all the data from a single stream contiguously on disk so
that RAID array readahead can be used effectively. Each additional
stream gets placed in different allocation groups within the
filesystem, thereby ensuring that we don't cross any streams. When
an AG fills up, we select a new AG for the stream that is not in
use.

The core of the functionality is the stream tracking - each inode
that we create in a directory needs to be associated with the
directories' stream. Hence every time we create a file, we look up
the directories' stream object and associate the new file with that
object.

Once we have a stream object for a file, we use the AG that the
stream object point to for allocations. If we can't allocate in that
AG (e.g. it is full) we move the entire stream to another AG. Other
inodes in the same stream are moved to the new AG on their next
allocation (i.e. lazy update).

Stream objects are kept in a cache and hold a reference on the
inode. Hence the inode cannot be reclaimed while there is an
outstanding stream reference. This means that on unlink we need to
remove the stream association and we also need to flush all the
associations on certain events that want to reclaim all unreferenced
inodes (e.g.  filesystem freeze).

Fix to prevent the notorious 'NULL files' problem after a crash.

The problem that has been addressed is that of synchronising updates of
the file size with writes that extend a file.  Without the fix the update
of a file's size, as a result of a write beyond eof, is independent of
when the cached data is flushed to disk.  Often the file size update would
be written to the filesystem log before the data is flushed to disk.  When
a system crashes between these two events and the filesystem log is
replayed on mount the file's size will be set but since the contents never
made it to disk the file is full of holes.  If some of the cached data was
flushed to disk then it may just be a section of the file at the end that
has holes.

There are existing fixes to help alleviate this problem, particularly in
the case where a file has been truncated, that force cached data to be
flushed to disk when the file is closed.  If the system crashes while the
file(s) are still open then this flushing will never occur.

The fix that we have implemented is to introduce a second file size, called
the in-memory file size, that represents the current file size as viewed by
the user.  The existing file size, called the on-disk file size, is the one
that get's written to the filesystem log and we only update it when it is
safe to do so.  When we write to a file beyond eof we only update the in-
memory file size in the write operation.  Later when the I/O operation, that
flushes the cached data to disk completes, an I/O completion routine will
update the on-disk file size.  The on-disk file size will be updated to the
maximum offset of the I/O or to the value of the in-memory file size if the
I/O includes eof.

In actual allocation of file system blocks and freeing extents, the transaction
within each such operation may involve multiple locking of AGF buffer. While the
freeing extent function has sorted the extents based on AGF number before entering
into transaction, however, when the file system space is very limited, the allocation
of space would try every AGF to get space allocated, this could potentially cause
out-of-order locking, thus deadlock could happen. This fix mitigates the scarce space
for allocation by setting aside a few blocks without reservation, and avoid deadlock
by maintaining ascending order of AGF locking.
Ensure no out-of-order locking of AGF in specifying allocation type for calling 
xfs_alloc_vextent.

Add parameters to xfs_bmapi() and xfs_bunmapi() to have them
report the range spanned by modifications to the in-core extent
map.  Add XFS_BUNMAPI() and XFS_SWAP_EXTENTS() macros that call
xfs_bunmapi() and xfs_swap_extents() via the ioops vector.
Change all calls that may modify the in-core extent map for the
data fork to go through the ioops vector.  This allows a cache
of extent map data to be kept in sync.
Add parameter to xfs_bmapi() and xfs_bunmapi() and their helper functions
which change the in-core extent list.  If not NULL, on return from
xfs_bmapi()/xfs_bunmapi() the value will be the offset and range covered
by any changes made to the in-core extent list, measured in blocks, and
rounded to extent boundaries.
Rewrite xfs_bmap_add_extent_hole_real() to remove exits from the middle

There are a few problems with the new xfs_bmap_search_multi_extents()
wrapper function that I introduced in mod xfs-linux:xfs-kern:207393a.
The function was added as a wrapper around xfs_bmap_do_search_extents()
to avoid breaking the top-of-tree CXFS interface.  The idea of the
function was basically to extract the target extent buffer (if muli-
level extent allocation mode), then call xfs_bmap_do_search_extents()
with either a pointer to the first extent in the target buffer or a
pointer to the first extent in the file, depending on which extent
mode was being used.  However, in addition to locating the target
extent record for block bno, xfs_bmap_do_search_extents() also sets
four parameters needed by the caller: *lastx, *eofp, *gotp, *prevp.

Passing only the target extent buffer to xfs_bmap_do_search_extents()
causes *eofp to be set incorrectly if the extent is at the end of the
target list but there are actually more extents in the next er_extbuf.
Likewise, if the extent is the first one in the buffer but NOT the
first in the file, *prevp is incorrectly set to NULL.  Adding the
needed functionality to xfs_bmap_search_multi_extents() to re-set
any incorrectly set fields is redundant and makes the call to
xfs_bmap_do_search_extents() not make much sense when multi-level
extent allocation mode is being used.

This mod basically extracts the two functional components from
xfs_bmap_do_search_extents(), with the intent of obsoleting/removing
xfs_bmap_do_search_extents() after the CXFS mult-level in-core extent
changes are checked in.  The two components are:  1) The binary search
to locate the target extent record, and 2) Setting the four parameters
needed by the caller (*lastx, *eofp, *gotp, *prevp).

Component 1:
I created a new function in xfs_inode.c called xfs_iext_bno_to_ext(),
which executes the binary search to find the target extent record.
xfs_bmap_search_multi_extents() has been modified to call
xfs_iext_bno_to_ext() rather than xfs_bmap_do_search_extents().

Component 2:
The parameter setting functionality has been added to
xfs_bmap_search_multi_extents(), eliminating the need for
xfs_bmap_do_search_extents().

These changes make the removal of xfs_bmap_do_search_extents() trival
once the CXFS changes are in place.  They also allow us to maintain
the current XFS interface, using the new search function introduced
in mod xfs-linux:xfs-kern:207393a.
Modify xfs_bmap_search_multi_extents() to call the new
xfs_iext_bno_to_ext() binary search function, then set the four
parameters needed by the caller.  Remove the call to
xfs_bmap_do_search_extents(), which will eventually be removed.

This mod introduces multi-level in-core file extent functionality,
building upon the new layout introduced in mod xfs-linux:xfs-kern:207390a.

The new multi-level extent allocations are only required for heavily
fragmented files, so the old-style linear extent list is used on files
until the extents reach a pre-determined size of 4k. 4k buffers are
used because this is the system page size on Linux i386 and systems
with larger page sizes don't seem to gain much, if anything, by using
their native page size as the extent buffer size. Also, using 4k extent
buffers everywhere provides a consistent interface for CXFS across
different platforms.

The 4k extent buffers are managed by an indirection array (xfs_ext_irec_t)
which is basically just a pointer array with a bit of extra information
to keep track of the number of extents in each buffer as well as the
extent offset of each buffer.

Major changes include:

- Add multi-level in-core file extent functionality to the xfs_iext_
  subroutines introduced in mod:  xfs-linux:xfs-kern:207390a

- Introduce 13 new subroutines which add functionality for multi-level
  in-core file extents:
        xfs_iext_add_indirect_multi()
        xfs_iext_remove_indirect()
        xfs_iext_realloc_indirect()
        xfs_iext_indirect_to_direct()
        xfs_iext_bno_to_irec()
        xfs_iext_idx_to_irec()
        xfs_iext_irec_init()
        xfs_iext_irec_new()
        xfs_iext_irec_remove()
        xfs_iext_irec_compact()
        xfs_iext_irec_compact_pages()
        xfs_iext_irec_compact_full()
        xfs_iext_irec_update_extoffs()
- Add a new subroutine called xfs_bmap_search_multi_extents(), which locates
  the target extent buffer, if in multi-level allocation mode, then calls
  xfs_bmap_do_search_extents() with either the target extent list or the
  direct extent list (depending on which allocation mode is being used).
- Modify xfs_bmap_search_extents() to call xfs_bmap_search_multi_extents()
  rather than xfs_bmap_do_search_extents().

This mod re-organizes some of the in-core file extent code to prepare
for an upcoming mod which will introduce multi-level in-core extent
allocations. Although the in-core extent management is using a new
code path in this mod, the functionality remains the same.

Major changes include:

- Introduce 10 new subroutines which re-orgainze the existing code but
  do NOT change functionality:
        xfs_iext_get_ext()
        xfs_iext_insert()
        xfs_iext_add()
        xfs_iext_remove()
        xfs_iext_remove_inline()
        xfs_iext_remove_direct()
        xfs_iext_realloc_direct()
        xfs_iext_direct_to_inline()
        xfs_iext_inline_to_direct()
        xfs_iext_destroy()
- Remove 2 subroutines (functionality moved to new subroutines above):
        xfs_iext_realloc() -replaced by xfs_iext_add() and xfs_iext_remove()
        xfs_bmap_insert_exlist() - replaced by xfs_iext_insert()
        xfs_bmap_delete_exlist() - replaced by xfs_iext_remove()
- Replace all hard-coded (indexed) extent assignments with a call to
  xfs_iext_get_ext()
- Replace all extent record pointer arithmetic (ep++, ep--, base + lastx,..)
  with calls to xfs_iext_get_ext()
- Update comments to remove the idea of a single "extent list" and
  introduce "extent record" terminology instead
- Replace indexed extent assignments with calls to xfs_iext_get_ext()
- Remove xfs_bmap_insert_exlist() and xfs_bmap_delete_exlist() and
  replace all calls by xfs_iext_insert() and xfs_iext_remove(),
  respectively.
- Update documentation and replace "extent list" terminology with
  "extent record"

Switch xfs from using a big endian internal representation for
the in memory copy of extents to a host byte order representation.
The internal extents are read in once, then modified seperately
from the on disk ones. Since we search and manipulate the extents
multiple times, it is cheaper to convert them to host byte order
once and then keep them in that format. Worth about 5 to 10%
reduction in cpu time for some loads. Complicated by the fact
that the in memory extents are written out to the log sometimes,
and when expanding extents are used to write out the initial
block of extents.
endian flip extents when reading in from disk, and when
going from in inode extents to a leaf block of extents.

Add lots of new code. OK, it's just debugging code but it is
very useful in identifying btree corruption in extent lists.
The new code walks btree leaves and analyzes btree nodes to see
if offsets/keys are in order and no dup blocks. All the ode
is off unless -DXFSDEBUG and -DDEBUG is turned on.
TO turn on, simply defines these and all extent additions into
btree format will check for consistency.

  set prod to 1 and try again, i.e. take what we can get, living with the

  Otherwise we'll loop from xfs_bmapi since this situation isn't supposed
  to happen.

Altered xfs_bmap_alloc() to traverse the agfs to find the longest
available space and to use that to set the minimum allocation size for the
first pass through the space allocator code. With this change we are doing a
better job of ensuring that the request will be satisfied in the first
loop through the code, and will result in fewer, longer extents being
allocated. Bug - 388854.
