From 9d23fc8575de7012b8853bd6fefe10534665de2f Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Tue, 29 Oct 2013 22:11:48 +1100 Subject: xfs: vectorise directory data operations Following from the initial patches to vectorise the shortform directory encode/decode operations, convert half the data block operations to use the vector. The rest will be done in a second patch. This further reduces the size of the built binary: text data bss dec hex filename 794490 96802 1096 892388 d9de4 fs/xfs/xfs.o.orig 792986 96802 1096 890884 d9804 fs/xfs/xfs.o.p1 792350 96802 1096 890248 d9588 fs/xfs/xfs.o.p2 789293 96802 1096 887191 d8997 fs/xfs/xfs.o.p3 Signed-off-by: Dave Chinner Reviewed-by: Christoph Hellwig Signed-off-by: Ben Myers --- fs/xfs/xfs_dir2_sf.c | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) (limited to 'fs/xfs/xfs_dir2_sf.c') diff --git a/fs/xfs/xfs_dir2_sf.c b/fs/xfs/xfs_dir2_sf.c index ec0d39b5fa12..953e19479151 100644 --- a/fs/xfs/xfs_dir2_sf.c +++ b/fs/xfs/xfs_dir2_sf.c @@ -251,11 +251,11 @@ xfs_dir2_block_to_sf( dp->d_ops->sf_put_ino(sfp, sfep, be64_to_cpu(dep->inumber)); dp->d_ops->sf_put_ftype(sfep, - xfs_dir3_dirent_get_ftype(mp, dep)); + dp->d_ops->data_get_ftype(dep)); sfep = dp->d_ops->sf_nextentry(sfp, sfep); } - ptr += xfs_dir3_data_entsize(mp, dep->namelen); + ptr += dp->d_ops->data_entsize(dep->namelen); } ASSERT((char *)sfep - (char *)sfp == size); xfs_dir2_sf_check(args); @@ -473,12 +473,12 @@ xfs_dir2_sf_addname_hard( * to insert the new entry. * If it's going to end up at the end then oldsfep will point there. */ - for (offset = xfs_dir3_data_first_offset(mp), + for (offset = dp->d_ops->data_first_offset(), oldsfep = xfs_dir2_sf_firstentry(oldsfp), - add_datasize = xfs_dir3_data_entsize(mp, args->namelen), + add_datasize = dp->d_ops->data_entsize(args->namelen), eof = (char *)oldsfep == &buf[old_isize]; !eof; - offset = new_offset + xfs_dir3_data_entsize(mp, oldsfep->namelen), + offset = new_offset + dp->d_ops->data_entsize(oldsfep->namelen), oldsfep = dp->d_ops->sf_nextentry(oldsfp, oldsfep), eof = (char *)oldsfep == &buf[old_isize]) { new_offset = xfs_dir2_sf_get_offset(oldsfep); @@ -555,8 +555,8 @@ xfs_dir2_sf_addname_pick( mp = dp->i_mount; sfp = (xfs_dir2_sf_hdr_t *)dp->i_df.if_u1.if_data; - size = xfs_dir3_data_entsize(mp, args->namelen); - offset = xfs_dir3_data_first_offset(mp); + size = dp->d_ops->data_entsize(args->namelen); + offset = dp->d_ops->data_first_offset(); sfep = xfs_dir2_sf_firstentry(sfp); holefit = 0; /* @@ -568,7 +568,7 @@ xfs_dir2_sf_addname_pick( if (!holefit) holefit = offset + size <= xfs_dir2_sf_get_offset(sfep); offset = xfs_dir2_sf_get_offset(sfep) + - xfs_dir3_data_entsize(mp, sfep->namelen); + dp->d_ops->data_entsize(sfep->namelen); sfep = dp->d_ops->sf_nextentry(sfp, sfep); } /* @@ -629,7 +629,7 @@ xfs_dir2_sf_check( mp = dp->i_mount; sfp = (xfs_dir2_sf_hdr_t *)dp->i_df.if_u1.if_data; - offset = xfs_dir3_data_first_offset(mp); + offset = dp->d_ops->data_first_offset(); ino = dp->d_ops->sf_get_parent_ino(sfp); i8count = ino > XFS_DIR2_MAX_SHORT_INUM; @@ -641,7 +641,7 @@ xfs_dir2_sf_check( i8count += ino > XFS_DIR2_MAX_SHORT_INUM; offset = xfs_dir2_sf_get_offset(sfep) + - xfs_dir3_data_entsize(mp, sfep->namelen); + dp->d_ops->data_entsize(sfep->namelen); ASSERT(dp->d_ops->sf_get_ftype(sfep) < XFS_DIR3_FT_MAX); } ASSERT(i8count == sfp->i8count); -- cgit v1.2.2
