Revision 2d7c820e56ce83b23daee9eb5343730fb309418e authored by Hidehiro Kawai on 22 October 2008, 21:15:01 UTC, committed by Linus Torvalds on 23 October 2008, 15:55:01 UTC 
ext3: add checks for errors from jbd
 
If the journal has aborted due to a checkpointing failure, we have to
keep the contents of the journal space.  Otherwise, the filesystem will
lose uncheckpointed metadata completely and become inconsistent.  To
avoid this, we need to keep needs_recovery flag if checkpoint has
failed.

With this patch, ext3_put_super() detects a checkpointing failure from
the return value of journal_destroy(), then it invokes ext3_abort() to
make the filesystem read only and keep needs_recovery flag.  Errors
from journal_flush() are also handled by this patch in some places.
