[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 <sandeen@sandeen.net> Signed-off-by: David Chinner <dgc@sgi.com> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>
