Message-ID: <48CD7FC3.4050807@redhat.com> Date: Sun, 14 Sep 2008 14:18:59 -0700 From: Eric Sandeen <sandeen@...hat.com> To: ext4 development <linux-ext4@...r.kernel.org> Subject: [PATCH] properly show journal checksum/async options The journal_checksum option is not being displayed in /proc/mounts ... add this to the show_options() output, but only if journal_async_commit is not specified, as that enables journal_checksum internally. Signed-off-by: Eric Sandeen <sandeen@...hat.com> --- (Aside: this reminds me that we only show non-default options in show_options; has there been any discussion of whether these should be defaults?)
