The patch titled
oom: less memdie
has been removed from the -mm tree. Its filename was
oom-less-memdie.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: oom: less memdie
From: Nick Piggin <npiggin@xxxxxxx>
Don't cause all threads in all other thread groups to gain TIF_MEMDIE
otherwise we'll get a thundering herd eating our memory reserve. This may not
be the optimal scheme, but it fits our policy of allowing just one TIF_MEMDIE
in the system at once.
