Hi all,

A tiny race about JBD2 has aborted to jbd2_journal_flush,

because of unstable storage link and I/O stress.

while JBD2 state is aborted, have been -EIO error,

may cause all cluster nodes hung. so I thinks

JBD2 has aborted the journal, ocfs2 cannot continue and trigger ocfs2_abort.

Thanks, Any ideas about this patch?
