I removed the global VM_is_OOM to keep the fixes to the minimum required to not be kernel-crashing, I adapted to the introduction of the zone-oom-lock bitflag, so with this update I hopefully have a better chance for merging. Despite the lack of VM_is_OOM perfect oom-killing serialization, and the need to avoid waiting forever on TIF_MEMDIE to prevent deadlocks, in practice with swap it seem not to generate bad spurious kills and it avoids the deadlock as well as my older patchset. We can always perfect this later with feedback coming from do_exit. Thanks. Andrea -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
