| |
Thierry reported offline that the strict check "mm: compaction: Iron out isolate_freepages_block() and isolate_freepages_range() -fix1" check is still too strict because it's possible for more pages to be isolated than required. This patch corrects the check.
There are still CMA-related problems but they are "somewhere else" yet to be determined.
