Subject: mm: page_cgroup: rename file to mm/swap_cgroup.c
X-Git-Tag: omap-for-v3.19/fixes-rc1~142^2~110
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5d1ea48bdde67898e87d6d8f511fd097fa64c749;p=pandora-kernel.git

mm: page_cgroup: rename file to mm/swap_cgroup.c

Now that the external page_cgroup data structure and its lookup is gone,
the only code remaining in there is swap slot accounting.

Rename it and move the conditional compilation into mm/Makefile.
