From 71ddabb94a623d1e16e7e66898bf439ff78ecc41 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Fri, 23 Nov 2007 16:29:42 +1100 Subject: [XFS] optimize XFS_IS_REALTIME_INODE w/o realtime config Use XFS_IS_REALTIME_INODE in more places, and #define it to 0 if CONFIG_XFS_RT is off. This should be safe because mount checks in xfs_rtmount_init: so if we get mounted w/o CONFIG_XFS_RT, no realtime inodes should be encountered after that. Defining XFS_IS_REALTIME_INODE to 0 saves a bit of stack space, presumeably gcc can optimize around the various "if (0)" type checks: xfs_alloc_file_space -8 xfs_bmap_adjacent -16 xfs_bmapi -8 xfs_bmap_rtalloc -16 xfs_bunmapi -28 xfs_free_file_space -64 xfs_imap +8 <-- ? hmm. xfs_iomap_write_direct -12 xfs_qm_dqusage_adjust -4 xfs_qm_vop_chown_reserve -4 SGI-PV: 971186 SGI-Modid: xfs-linux-melb:xfs-kern:30014a Signed-off-by: Eric Sandeen Signed-off-by: David Chinner Signed-off-by: Lachlan McIlroy --- fs/xfs/xfs_bmap_btree.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'fs/xfs/xfs_bmap_btree.c') diff --git a/fs/xfs/xfs_bmap_btree.c b/fs/xfs/xfs_bmap_btree.c index 32b49ec00fb5..c4181d85605c 100644 --- a/fs/xfs/xfs_bmap_btree.c +++ b/fs/xfs/xfs_bmap_btree.c @@ -2062,8 +2062,7 @@ xfs_bmbt_insert( pcur->bc_private.b.allocated; pcur->bc_private.b.allocated = 0; ASSERT((cur->bc_private.b.firstblock != NULLFSBLOCK) || - (cur->bc_private.b.ip->i_d.di_flags & - XFS_DIFLAG_REALTIME)); + XFS_IS_REALTIME_INODE(cur->bc_private.b.ip)); cur->bc_private.b.firstblock = pcur->bc_private.b.firstblock; ASSERT(cur->bc_private.b.flist == -- cgit v1.2.3
