use minleft when allocating in xfs_bmbt_split() The bmap btree split code relies on a previous data extent allocation (from xfs_bmap_btalloc()) to find an AG that has sufficient space to perform a full btree split, when inserting the extent. When converting unwritten extents we don't allocate a data extent so a btree split will be the first allocation. In this case we need to set minleft so the allocator will pick an AG that has space to complete the split(s).

shrink mrlock_t The writer field is not needed for non_DEBU builds so remove it. While we're at i also clean up the interface for is locked asserts to go through and xfs_iget.c helper with an interface like the xfs_ilock routines to isolated the XFS codebase from mrlock internals. That way we can kill mrlock_t entirely once rw_semaphores grow an islocked facility. Also remove unused flags to the ilock family of functions.

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 xfs_bmap_rtalloc -16 xfs_bunmapi -28 xfs_free_file_space -64 xfs_imap +8 <-- ? hmm. xfs_iomap_write_direct -12 xfs_qm_dqusage_adjust -4 xfs_qm_vop_chown_reserve -4 Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Merge of xfs-linux-melb:xfs-kern:30014a by kenmcd.

Fix transaction overrun during writeback. Prevent transaction overrun in xfs_iomap_write_allocate() if we race with a truncate that overlaps the delalloc range we were planning to allocate. If we race, we may allocate into a hole and that requires block allocation. At this point in time we don't have a reservation for block allocation (apart from metadata blocks) and so allocating into a hole rather than a delalloc region results in overflowing the transaction block reservation. Fix it by only allowing a single extent to be allocated at a time. Merge of xfs-linux-melb:xfs-kern:30005a by kenmcd. Only allow xfs_iomap_write_allocate to allocate a single extent at a time to prevent races with truncate from causing unreserved allocation and hence transaction overruns.

kill unnessecary ioops indirection Currently there is an indirection called ioops in the XFS data I/O path.

Prevent ENOSPC from aborting transactions that need to succeed
During delayed allocation extent conversion or unwritten extent
conversion, we need to reserve some blocks for transactions
reservations. We need to reserve these blocks in case a btree
split occurs and we need to allocate some blocks.
Unfortunately, we've only ever reserved the number of data blocks we
are allocating, so in both the unwritten and delalloc case we can
get ENOSPC to the transaction reservation. This is bad because in
both cases we cannot report the failure to the writing application.
The fix is two-fold:
1 - leverage the reserved block infrastructure XFS already
has to reserve a small pool of blocks by default to allow
specially marked transactions to dip into when we are at
ENOSPC.
Default setting is min(5%, 1024 blocks).
2 - convert critical transaction reservations to be allowed
to dip into this pool. Spots changed are delalloc
conversion, unwritten extent conversion and growing a
filesystem at ENOSPC.
This also allows growing the filesytsem to succeed at ENOSPC.
Merge of xfs-linux-melb:xfs-kern:28865a by kenmcd.
Allow unwritten extent conversion and delayed allocation tranactions
to use reserved space instead of silently failing at ENOSPC.

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. Merge of xfs-linux-melb:xfs-kern:28322a by kenmcd. Fix to prevent the notorious 'NULL files' problem after a crash.

Remove unused header files for MAC and CAP checking functionality. xfs_mac.h and xfs_cap.h provide definitions and macros that aren't used anywhere in XFS at all. They are left-overs from "to be implement at some point in the future" functionality that Irix XFS has.

xfs_iomap_write_delay() was doing speculative allocations without checking if there were any real blocks already in the speculative allocation area. This could result in an allocation that overlaps pre-allocated space. This would result in an ASSERT failure in debug kernels, or invalid output from xfs_bmap. The code will now only do speculative allocation if we are writing beyond the current allocation eof. xfs_iomap_write_delay() was doing speculative allocations without checking if there were any real blocks already in the speculative allocation area.
