It works for me on XFS.  But I don't really understand why, as the fault
handler doesn't look very different.

Maybe the problem is that in ext4_journal_start_sb will fail on
a read-only fs?

Even for xfs/ext2 it would seem odd that things like sb_start_pagefault
just work.

These checks all fail for me..
