Ocfs2 devel - Apr 2015 - [PATCH 0/3] ocfs2: fix some inconsistency problems caused by jbd2_journal_restart()

I found that function jbd2_journal_restart() is called some places in
ocfs2 without keeping things consistently before. However, 
jbd2_journal_restart() may commit the handle's transaction and restart
another one. If the first transaction is committed successfully
while another not, it may cause filesystem inconsistency or read only.
This is an effort to fix this kind of problems.

Any comments are appreciated, thanks!
