Subject: [patch] ocfs2: remove unneeded NULL check
Date: Fri, 28 Nov 2014 08:30:40 +0000 [thread overview]
Message-ID: <20141128083040.GA10252@mwanda> (raw)
In 1faf289454b9 ('ocfs2_dlm: disallow a domain join if node maps
mismatch') then we introduced a new earlier NULL check so this one is
not needed. Also static checkers complain because we dereference it
first and then check for NULL.
