The patch titled Subject: mm/balloon_compaction: isolate balloon pages without lru_lock has been removed from the -mm tree. Its filename was mm-balloon_compaction-isolate-balloon-pages-without-lru_lock.patch This patch was dropped because an updated version will be merged ------------------------------------------------------ From: Konstantin Khlebnikov <k.khlebnikov@xxxxxxxxxxx> Subject: mm/balloon_compaction: isolate balloon pages without lru_lock LRU-lock isn't required for balloon page isolation. This check makes migration of some ballooned pages mostly impossible because isolate_migratepages_range() drops LRU lock periodically.
