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

  And a similar patch for JBD2...

-----

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).
