From: KOSAKI Motohiro Date: Thu, 24 Jul 2008 04:27:01 +0000 (-0700) Subject: page allocator: inline some __alloc_pages() wrappers X-Git-Tag: v2.6.27-rc1~831 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=e4048e5dc4aecec670f48ed007a28779f09cebd6;p=linux-2.6-omap-h63xx.git page allocator: inline some __alloc_pages() wrappers Two zonelist patch series rewrote __page_alloc() largely. Now, it is just a wrapper function. Inlining them will save a function call.
