The patch titled
coredump: make mm->core_state visible to ->core_dump()
has been removed from the -mm tree. Its filename was
coredump-make-mm-core_state-visible-to-core_dump.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: coredump: make mm->core_state visible to ->core_dump()
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Move the "struct core_state core_state" from coredump_wait() to
do_coredump(), this makes mm->core_state visible to binfmt->core_dump().
