From: Hui Su Date: Tue, 15 Dec 2020 03:12:42 +0000 (-0800) Subject: mm/compaction: move compaction_suitable's comment to right place X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2b1a20c3afbc0279cbe57b0f19748081eba0881b;p=linux.git mm/compaction: move compaction_suitable's comment to right place Since commit 837d026d560c ("mm/compaction: more trace to understand when/why compaction start/finish"), the comment place is not suitable. So move compaction_suitable's comment to right place.
