Subject: [PATCH] binfmt: move more stuff undef CONFIG_COREDUMP
Date: Sun, 13 Feb 2022 22:25:20 +0300	[thread overview]
Message-ID: <YglbIFyN+OtwVyjW@localhost.localdomain> (raw)

struct linux_binfmt::core_dump and struct min_coredump::min_coredump
are used under CONFIG_COREDUMP only. Shrink those embedded configs
a bit.
