-Subject: [PATCH 056/134] mm: Check if any page in a pageblock is reserved before marking it MIGRATE_RESERVE
-
-This fixes a problem where the first pageblock got marked MIGRATE_RESERVE even
-though it only had a few free pages. This in turn caused no contiguous memory
-to be reserved and frequent kswapd wakeups that emptied the caches to get more
-contiguous memory.
