Subject: [Ocfs2-devel] [PATCH 0/2] ocfs2: fix a deadlock case
Date: Fri, 21 Jan 2022 15:12:03 +0800 [thread overview]
Message-ID: <20220121071205.100648-1-joseph.qi@linux.alibaba.com> (raw)
This is trying to fix a deadlock case in ocfs2.
We firstly export jbd2 symbols jbd2_journal_[grab|put]_journal_head as
preparation and later use them in ocfs2 insread of
jbd_[lock|unlock]_bh_journal_head to fix the deadlock.
