From: Joonsoo Kim <iamjoonsoo.kim@xxxxxxx> It's not necessary to initialized page_owner with holding the zone lock. It would cause more contention on the zone lock although it's not a big problem since it is just debug feature. But, it is better than before so do it. This is also preparation step to use stackdepot in page owner feature. Stackdepot allocates new pages when there is no reserved space and holding the zone lock in this case will cause deadlock.
I have same concerns here as for Patch 1/6. Thanks. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ . Don't email: <a href=mailto:"dont@xxxxxxxxx";> email@xxxxxxxxx </a>
