Subject: mm/page_alloc: drop a misleading __always_inline
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=d231522bf07287c5bcf7c6af6960f476663324b5;p=thirdparty%2Flinux.git

mm/page_alloc: drop a misleading __always_inline

get_pfnblock_migratetype() is called from outside page_alloc.c, so it
cannot always be inlined.  Remove the annotation to avoid misleading
readers.

At least in my minimal config, with GCC, this doesn't change
mm/page_alloc.o at all.
