Subject: ext3: abort ext3 if the journal has aborted
From: Hidehiro Kawai <hidehiro.kawai.ez@...achi.com>
If the journal has aborted due to a checkpointing failure, we have to keep
the contents of the journal space. ext3_put_super() detects the journal
abort, then it invokes ext3_abort() to make the filesystem read only and
keep needs_recovery flag.
