      xfs: remove m_attroffset · 1a5902c5
      由 Christoph Hellwig 提交于 
      With the upcoming v3 inodes the default attroffset needs to be calculated
for each specific inode, so we can't cache it in the superblock anymore.

Also replace the assert for wrong inode sizes with a proper error check
also included in non-debug builds.  Note that the ENOSYS return for
that might seem odd, but that error is returned by xfs_mount_validate_sb
for all theoretically valid but not supported filesystem geometries.

      xfs: make symbols static · 3180e66d
      由 Hannes Eder 提交于 
      Instead of the keyword 'static' the macro 'STATIC' is used, so the
symbols are still global with CONFIG_XFS_DEBUG.

Fix this sparse warnings:
  fs/xfs/linux-2.6/xfs_super.c:638:1: warning: symbol 'xfs_blkdev_get' was not declared. Should it be static?
  fs/xfs/linux-2.6/xfs_super.c:655:1: warning: symbol 'xfs_blkdev_put' was not declared. Should it be static?
  fs/xfs/linux-2.6/xfs_super.c:876:1: warning: symbol 'xfsaild' was not declared. Should it be static?
  fs/xfs/xfs_bmap.c:6208:1: warning: symbol 'xfs_check_block' was not declared. Should it be static?

      [XFS] Add new getbmap flags. · 5af317c9
      由 Eric Sandeen 提交于 
      This adds a new output flag, BMV_OF_LAST to indicate if we've hit
the last extent in the inode.  This potentially saves an extra call
from userspace to see when the whole mapping is done.

It also adds BMV_IF_DELALLOC and BMV_OF_DELALLOC to request, and
indicate, delayed-allocation extents.  In this case bmv_block
is set to -2 (-1 was already taken for HOLESTARTBLOCK; unfortunately
these are the reverse of the in-kernel constants.)

These new flags facilitate addition of the new fiemap interface.

Rather than adding sh_delalloc, remove sh_unwritten & just test
the flags directly.

      [XFS] convert xfs_getbmap to take formatter functions · 8a7141a8
      由 Eric Sandeen 提交于 
      Preliminary work to hook up fiemap, this allows us to pass in an
arbitrary formatter to copy extent data back to userspace.

The formatter takes info for 1 extent, a pointer to the user "thing*"
and a pointer to a "filled" variable to indicate whether a userspace
buffer did get filled in (for fiemap, hole "extents" are skipped).

I'm just using the getbmapx struct as a "common denominator" because
as far as I can see, it holds all info that any formatters will care
about.

("*thing" because fiemap doesn't pass the user pointer around, but rather
has a pointer to a fiemap info structure, and helpers associated with it)

      [XFS] Fix double free of log tickets · cc09c0dc
      由 Dave Chinner 提交于 
      When an I/O error occurs during an intermediate commit on a rolling
transaction, xfs_trans_commit() will free the transaction structure
and the related ticket. However, the duplicate transaction that
gets used as the transaction continues still contains a pointer
to the ticket. Hence when the duplicate transaction is cancelled
and freed, we free the ticket a second time.

Add reference counting to the ticket so that we hold an extra
reference to the ticket over the transaction commit. We drop the
extra reference once we have checked that the transaction commit
did not return an error, thus avoiding a double free on commit
error.

Credit to Nick Piggin for tripping over the problem.

      [XFS] shrink mrlock_t · 579aa9ca
      由 Christoph Hellwig 提交于 
      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.
