Subject: mm/compaction.c: update comment about zone lock in isolate_freepages_block
Since commit f40d1e4 ("mm: compaction: acquire the zone->lock as late as
possible"), isolate_freepages_block() takes the zone->lock itself. The
function description however still states that the zone->lock must be
held.
This patch removes this outdated statement.
