[PATCH 0/2] coredump: make the coredumping process visible to oom kill

[Oleg Nesterov]

On top of coredump-kill-mm-core_done.patch.

The last patches which change the coredump "thread management", the next
step is to make coredump interruptible.

I am worried the recent changes can break elf_fdpic_core_dump(), I can't
test it. Hopefully, in that case the fixes should be trivial.

Oleg.

I can't apply your patch 2/2.  Is there another patch missing?
