More raid5 issues: Kernel panic running xfs_db

[Lars Kellogg-Stedman <lars@xxxxxxxxxxxxx>]

I got a kernel panic trying to run xfs_admin earlier today to label some
filesytems.  Further experiments revealed:

  (a) The panic is apparently caused when xfs_admin calls xfs_db, and
  (b) The panic only occurs on the soft raid5 volume.  Other filesystems
      presented no problems.

The kernel panic looked like:

  Mar  6 20:08:40 flowers kernel: Kernel panic: Invalid blocksize passed to 
set_blocksize

Which looks like it's coming from fs/buffer.c.

The xfs device that triggered this was /dev/md/0, which is a soft raid5
volume over 4 scsi disks.
