Subject: [PATCH 04/36] xfs: kill xfs_alloc_pagf_init()
Date: Fri, 3 Dec 2021 11:00:39 +1100 [thread overview]
Message-ID: <20211203000111.2800982-5-david@fromorbit.com> (raw)
In-Reply-To: <20211203000111.2800982-1-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
Trivial wrapper around xfs_alloc_read_agf(), can be easily replaced
by passing a NULL agfbp to xfs_alloc_read_agf().
Signed-off-by: Dave Chinner <dchinner@redhat.com>
