[Ocfs2-devel] [PATCH] ocfs2: unlock inode if deleting inode from orphan fail

[Joseph Qi]

From: Guozhonghua <guozhonghua@h3c.com>

When doing append direct io cleanup, if deleting inode fails, it goes
out without unlocking inode, which will cause the inode deadlock.
This issue was introduced by commit cf1776a9e834("ocfs2: fix a tiny
race when truncate dio orohaned entry").
