      [XFS] fix error inversion problems with data flushing · 2e656092
      由 Dave Chinner 提交于 
      XFS gets the sign of the error wrong in several places when
gathering the error from generic linux functions. These functions
return negative error values, while the core XFS code returns
positive error values. Hence when XFS inverts the error to be
returned to the VFS, it can incorrectly invert a negative
error and this error will be ignored by the syscall return.

Fix all the problems related to calling filemap_* functions.

Problem initially identified by Nick Piggin in xfs_fsync().

      [XFS] fix spurious gcc warnings · 65795910
      由 Christoph Hellwig 提交于 
      Some recent gcc warnings don't like passing string variables to
printf-like functions without using at least a "%s" format string.
Change the two occurances of that in xfs to please gcc.

      [XFS] allow inode64 mount option on 32 bit systems · 6c31b93a
      由 Christoph Hellwig 提交于 
      Now that we've stopped using the Linux inode cache when can trivally
support the inode64 mount option on 32bit architectures.  As far as the
kernel and most userspace is concerned this works perfectly, but
applications still using really old stat and readdir interfaces will get
an EOVERFLOW error when hitting an inode number not fitting into 32
bits (that problem of course also exists when using these applications
on a 64bit kernel).

Note that because inode64 is simply a mount option we can currently
mount a filesystem having > 32 bit inode numbers and cause a variety of
problems, all this is solved but this patch which enables XFS_BIG_INUMS,
even when inode64 is not used.

      [XFS] wire up ->open for directories · f999a5bf
      由 Christoph Hellwig 提交于 
      Currently there's no ->open method set for directories on XFS.  That
means we don't perform any check for opening too large directories
without O_LARGEFILE, we don't check for shut down filesystems, and we
don't actually do the readahead for the first block in the directory.

Instead of just setting the directories open routine to xfs_file_open
we merge the shutdown check directly into xfs_file_open and create
a new xfs_dir_open that first calls xfs_file_open and then performs
the readahead for block 0.

      [XFS] fix NULL pointer dereference in xfs_log_force_umount · bac8dca9
      由 Christoph Hellwig 提交于 
      xfs_log_force_umount may be called very early during log recovery where

If we fail a buffer read in xlog_recover_do_inode_trans we abort the mount.
But at that point log recovery has started delayed writeback of inode
buffers.   As part of the aborted mount we try to flush out all delwri
buffers, but at that point we have already freed the superblock, and set
mp->m_sb_bp to NULL, and xfs_log_force_umount which gets called after
the inode buffer writeback trips over it.

Make xfs_log_force_umount a little more careful when accessing mp->m_sb_bp
to avoid this.
