Subject: [PATCH 07/50] xfs: pass perag to xfs_read_agf
Date: Sat, 11 Jun 2022 11:26:16 +1000	[thread overview]
Message-ID: <20220611012659.3418072-8-david@fromorbit.com> (raw)
In-Reply-To: <20220611012659.3418072-1-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

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