Bug description:
  SRU Justification:

  Impact: The patches backported to fix CVE-2010-2943 caused a
  regression for xfsdump.

  Fix: Backporting one more patch from upstream is fixing the issue.

  Testcase:
   1. create an xfs filesystem with data (>~100MB). There is a compressed archive provided in comment #14.
   2. run "xfsdump -p10 -Ltest -Mdump -f outfile <mount>"
       Note: Hardy and earlier seem to require the path to the device, while later releases can handle the mount point.
  The xfsdump command aborts with SGI_FS_BULKSTAT errno = 22

  ---

  On our Ubuntu 10.04 LTS server running x86 code, this evening a kernel
  update was ready for installation. I updated the kernel, rebooted
  (IPL'ed), and proceeded with the backup which utilized xfsdump as we
  use the xfs filesystem. Four of the xfsdump received a never before
  seen error: SGI_FS_BULKSTAT errno = 22

  Output as follows:
  using file dump (drive_simple) strategy
  version 3.0.4 (dump format 3.0) - Running single-threaded
  level 0 dump of ldslnx01:/srv

  dump size (non-dir files) : 0 bytes
  NOTE: dump interrupted: 79 seconds elapsed: may resume later using -R option
  Dump Status: INTERRUPT

  This backup file did have some size to it. The other three, backing up
  smaller amounts of data, were all zero (0) length dump files.

  I rebooted to the prior kernel: $ uname -a
  Linux ldslnx01 2.6.32-26-generic-pae #48-Ubuntu SMP Wed Nov 24 10:31:20 UTC 2010 i686 GNU/Linux

  And the same backup gets to 100% success.

  Reboot to the new kernel, same failure.

  I think that fairly well illustrates that the problem exists only with
  the kernel update installed this evening.

  I did come across a reference to this problem on the SGI website:

  http://techpubs.sgi.com/library/tpl/cgi-bin/getdoc.cgi?coll=0650&db=relnotes&fname=/usr/relnotes/eoe
    1.6.17  Bugs fixed in IRIX 6.5.13
      + 816457:  xfsdump SGI_FS_BULKSTAT errno = 22	cxfs

  So evidently it is something that has been seen and corrected in IRIX.
