Subject: SLUB: add some more inlines and #ifdef CONFIG_SLUB_DEBUG
X-Git-Tag: v2.6.23-rc1~745
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=0c710013200e72b5e0bc680ff4ec6bdac53c5ce8;p=linux-2.6-omap-h63xx.git

SLUB: add some more inlines and #ifdef CONFIG_SLUB_DEBUG

Add #ifdefs around data structures only needed if debugging is compiled into
SLUB.

Add inlines to small functions to reduce code size.
