[PATCH] oom: handle current exiting
If current *is* exiting, it should actually be allowed to access reserved
memory rather than OOM kill something else. Can't do this via a straight
check in page_alloc.c because that would allow multiple tasks to use up
reserves. Instead cause current to OOM-kill itself which will mark it as
TIF_MEMDIE.
The current procedure of simply aborting the OOM-kill if a task is exiting can
lead to OOM deadlocks.
In the case of killing a PF_EXITING task, don't make a lot of noise about it.
This becomes more important in future patches, where we can "kill" OOM_DISABLE
tasks.
