Subject: fs/ocfs2/aops.c: test for IS_ERR rather than 0
X-Git-Tag: v2.6.26-rc1~1143^2~7
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=58dadcdbc2584db050969f9781727fc5a3f618db;p=linux-2.6-omap-h63xx.git

fs/ocfs2/aops.c: test for IS_ERR rather than 0

The function ocfs2_start_trans always returns either a valid pointer or a
value made with ERR_PTR, so its result should be tested with IS_ERR, not
with a test for 0.
