From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jan Kara Date: Mon, 20 Oct 2008 19:23:51 +0200 Subject: [Ocfs2-devel] [PATCH] ocfs2: Fix check of return value of ocfs2_start_trans() In-Reply-To: y References: y Message-ID: <12245234424005-git-send-email-jack@suse.cz> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ocfs2-devel@oss.oracle.com On failure, ocfs2_start_trans() returns values like ERR_PTR(-ENOMEM). Thus checks for !handle are wrong. Fix them to use IS_ERR().
