Subject[PATCH 1/5] mm: compaction: Update comment in try_to_compact_pages
Date
The comment about order applied when the check was
order > PAGE_ALLOC_COSTLY_ORDER which has not been the case since
[c5a73c3d: thp: use compaction for all allocation orders]. Fixing
the comment while I'm in the general area.
