Subject: [PATCH] exec: remove checks in __register_bimfmt()
Date: Tue, 25 May 2021 21:49:47 +0300 [thread overview]
Message-ID: <YK1Gy1qXaLAR+tPl@localhost.localdomain> (raw)
Delete NULL check, all callers pass valid pointer.
Delete ->load_binary check -- failure to provide hook in a custom module
will be very noticeable at the very first execve call.
