      [XFS] Hook up the fiemap ioctl. · f35642e2
      Eric Sandeen authored 
      This adds the fiemap inode_operation, which for us converts the
fiemap values & flags into a getbmapx structure which can be sent
to xfs_getbmap.  The formatter then copies the bmv array back into
the user's fiemap buffer via the fiemap helpers.

If we wanted to be more clever, we could also return mapping data
for in-inode attributes, but I'm not terribly motivated to do that
just yet.

      [XFS] Add new getbmap flags. · 5af317c9
      Eric Sandeen authored 
      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
      Eric Sandeen authored 
      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 uninitialised variable bug in dquot release. · 0924b585
      Dave Chinner authored 
      gcc is warning about an uninitialised variable in xfs_growfs_rt().
This is a false positive. Fix it by changing the scope of the
transaction pointer to wholly within the internal loop inside
the function.

While there, preemptively change xfs_growfs_rt_alloc() in the
same way as it has exactly the same structure as xfs_growfs_rt()
but gcc is not warning about it. Yet.

      [XFS] fix error inversion problems with data flushing · 2e656092
      Dave Chinner authored 
      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
      Christoph Hellwig authored 
      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
      Christoph Hellwig authored 
      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
      Christoph Hellwig authored 
      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
      Christoph Hellwig authored 
      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.
