Subject: mm/page_isolation.c: fix the function comments
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ec3b6882509188602dfaadf2814a9cca062f2786;p=openwrt%2Fstaging%2Fblogic.git

mm/page_isolation.c: fix the function comments

Commit fea85cff11de ("mm/page_isolation.c: return last tested pfn rather
than failure indicator") changed the meaning of the return value.  Let's
change the function comments as well.
