Subject: [PATCH 32/42] xfs: use xfs_bmap_longest_free_extent() in filestreams
Date: Fri, 10 Feb 2023 09:18:15 +1100 [thread overview]
Message-ID: <20230209221825.3722244-33-david@fromorbit.com> (raw)
In-Reply-To: <20230209221825.3722244-1-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
The code in xfs_bmap_longest_free_extent() is open coded in
xfs_filestream_pick_ag(). Export xfs_bmap_longest_free_extent and
call it from the filestreams code instead.
