Subject: [PATCH 08/32] xfs: make growfs initialise the AGFL header
Date: Mon, 12 Nov 2012 22:54:00 +1100 [thread overview]
Message-ID: <1352721264-3700-9-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1352721264-3700-1-git-send-email-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
For verification purposes, AGFLs need to be initialised to a known
set of values. For upcoming CRC changes, they are also headers that
need to be initialised. Currently, growfs does neither for the AGFLs
- it ignores them completely. Add initialisation of the AGFL to be
full of invalid block numbers (NULLAGBLOCK) to put the
infrastructure in place needed for CRC support.
Includes a comment clarification from Jeff Liu.
