From: Richard Kennedy Date: Thu, 28 Oct 2010 21:21:59 +0000 (-0400) Subject: fsnotify: remove alignment padding from fsnotify_mark on 64 bit builds X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d8c0fca68da25ca3df534dfb12ce628675c828e4;p=linux-beck.git fsnotify: remove alignment padding from fsnotify_mark on 64 bit builds 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.
