fs: inode - remove 8 bytes of padding on 64bits allowing 1 more objects/slab under slub
This removes 8 bytes of padding from struct inode on 64bit builds, and so allows 1 more object/slab in the inode_cache when using slub. Signed-off-by: Richard Kennedy <richard@rsk.demon.co.uk> ---- patch against 2.6.33-rc8 compiled & tested on x86_64 AMDX2 I've been running this patch for over a week with no obvious problems regards Richard Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
