Subject: [PATCH] Fix commit code to properly abort journal

  Hi,

  attached patch changes JBD commit code to properly record reason for
aborted journal (j_errno) and not just mark the journal as aborted. Andrew,
could you please queue the patch? Thanks.

We should really call journal_abort() and not __journal_abort_hard() in case
of errors. The latter call does not record the error in the journal superblock and
thus filesystem won't be marked as with errors later (and user could happily mount
it without any warning).
