Mike Snitzer noticed that ext3_mark_recovery_complete() doesn't
check checkpointing failure and it clears needs_recovery flag 
(thanks, Mike!).  I need an additional fix.

I also found ext3_quota_on() forces checkpointing by journal_flush()
but it doesn't check the error.  This will appear in 2.6.27-rc1,
so I'll send the revised patch set for 2.6.27-rc1 (it may be
a separate patch).

Thanks,
