Subject: [PATCH 06/36] xfs: pass perag to xfs_read_agi
Date: Fri,  3 Dec 2021 11:00:41 +1100	[thread overview]
Message-ID: <20211203000111.2800982-7-david@fromorbit.com> (raw)
In-Reply-To: <20211203000111.2800982-1-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

We have the perag in most palces we call xfs_read_agi, so pass the
perag instead of a mount/agno pair.

Signed-off-by: Dave Chinner <dchinner@redhat.com>
