Subject: [PATCH 26/32] db: re-enable write support for v5 filesystems.
Date: Mon, 30 Sep 2013 13:15:38 +1000	[thread overview]
Message-ID: <1380510944-8571-27-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1380510944-8571-1-git-send-email-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

As we can now verify and recalculate CRCs on IO, we can modify the
on-disk structures without corrupting the filesyste, This makes it
safe to turn write support on for v5 filesystems for the first time.
