Subject: [PATCH 3.2 40/61] mm/vmstat.c: fix wrong comment

3.2.96-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: SeongJae Park <sj38.park@...il.com>

commit f113e64121ba9f4791332248b315d9f57ee33a6b upstream.

Comment for pagetypeinfo_showblockcount() is mistakenly duplicated from
pagetypeinfo_show_free()'s comment.  This commit fixes it.
