Commit 736a4c11 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'for-linus-v3.9-rc1' of git://oss.sgi.com/xfs/xfs

Pull xfs update from Ben Myers:
 "Primarily bugfixes and a few cleanups:

   - fix(es) for compound buffers

   - remove unused XFS_TRANS_DEBUG routines

   - fix for dquot soft timer asserts due to overflow of d_blk_softlimit

   - don't zero allocation args structure members after they are memset(0)

   - fix for regression in dir v2 code introduced in commit 20f7e9f3

   - remove obsolete simple_strto<foo>

   - fix return value when filesystem probe finds no XFS magic, a
     regression introduced in 98021821.

   - remove boolean_t typedef completely

   - fix stack switch in __xfs_bmapi_allocate by moving the check for
     stack switch up into xfs_bmapi_write.

   - fix build error due to incomplete boolean_t removal

   - fix oops in _xfs_buf_find by validating that the requested block is
     within the filesystem bounds.

   - limit speculative preallocation near ENOSPC.

   - fix an unmount hang in xfs_wait_buftarg by freeing the
     xfs_buf_log_item in xfs_buf_item_unlock.

   - fix a possible use after free with AIO.

   - fix xfs_swap_extents after removal of xfs_flushinval_pages, a
     regression introduced in fb595814.

   - replace hardcoded 128 with log header size

   - add memory barrier before wake_up_bit in xfs_ifunlock

   - limit speculative preallocation on sparse files

   - fix xa_lock recursion bug introduced in 90810b9e

   - fix write verifier for symlinks"

Fixed up conflicts in fs/xfs/xfs_buf_item.c (due to bli_format rename in
commit 0f22f9d0 affecting the removed XFS_TRANS_DEBUG routines in
commit ec47eb6b).
