When patching in a newer LVM you have to watch out. XFS needs something
more of LVM for the blksize ioctl. If you patch in a newer LVM you
probably removed that.

The only conflict that JFS and XFS have is in fs.h which can be solved by
either finding the patch in the mailing list archive or handapplying the
rejected lines.

Have not been able to test the 2.4.6 patch yet.

See the thread in the mailinglist archives "XFS mary's JFS"
There were links to patches in there and discussion about both of them.

Because JFS probably uses just one blksize and XFS switches between
pagesize (4k) and 512bytes.
