[PATCH 20/20] fsnotify: remove alignment padding from fsnotify_markon 64 bit builds

From: Eric Paris
Date: Thu Oct 28 2010 - 17:34:12 EST


From: Richard Kennedy <richard@xxxxxxxxxxxxxxx>

Reorder struct fsnotfiy_mark to remove 8 bytes of alignment padding on 64
bit builds. Shrinks fsnotfiy_mark to 128 bytes allowing more objects per
slab in its kmem_cache and reduces the number of cachelines needed for
each structure.
