From 3d92c93b7065be28eda33f92681d2f1121fbf8bf Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 8 Nov 2019 15:01:39 -0800 Subject: [PATCH] xfs: devirtualize ->db_to_fdb and ->db_to_fdindex 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 Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
