Message-ID: <536A652C.7080509@redhat.com> Date: Wed, 07 May 2014 11:54:04 -0500 From: Eric Sandeen <sandeen@...hat.com> To: ext4 development <linux-ext4@...r.kernel.org> Subject: [PATCH] jbd2: prefix printks with JBD2: not JBD: I was looking at some debugging logs from a test on ext4, and wondered why I saw messages from JBD: not JBD2: This is why! Probably worth changing for consistency.
