The patch titled mm: document tree_lock->zone.lock lockorder has been removed from the -mm tree. Its filename was mm-document-tree_lock-zonelock-lockorder.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ Subject: mm: document tree_lock->zone.lock lockorder From: Nick Piggin <npiggin@xxxxxxx> zone->lock is quite an "inner" lock and mostly constrained to page alloc as well, so like slab locks, it probably isn't something that is critically important to document here. However unlike slab locks, zone lock could be used more widely in future, and page_alloc.c might possibly have more business to do tricky things with pagecache than does slab. So... I don't think it hurts to document it.
