Subject: [PATCH 20/20] fsnotify: remove alignment padding from fsnotify_mark on 64 bit builds
Date: Thu, 28 Oct 2010 17:33:31 -0400 [thread overview]
Message-ID: <20101028213331.24810.75808.stgit@paris.rdu.redhat.com> (raw)
In-Reply-To: <20101028213139.24810.34058.stgit@paris.rdu.redhat.com>
From: Richard Kennedy <richard@rsk.demon.co.uk>
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.
