Subject: [PATCH 18/34] xfs: devirtualize ->db_to_fdb and ->db_to_fdindex
Date: Fri, 1 Nov 2019 15:07:03 -0700 [thread overview]
Message-ID: <20191101220719.29100-19-hch@lst.de> (raw)
In-Reply-To: <20191101220719.29100-1-hch@lst.de>
Now that the max bests value is in struct xfs_da_geometry both instances
of ->db_to_fdb and ->db_to_fdindex are identical. Replace them with
local xfs_dir2_db_to_fdb and xfs_dir2_db_to_fdindex functions in
xfs_dir2_node.c.
Signed-off-by: Christoph Hellwig <hch@lst.de>
