Subject: [PATCH 09/14] signal: Move audit_core_dumps from do_coredump into get_signal
Date: Fri, 03 Jul 2026 16:41:57 -0500	[thread overview]
Message-ID: <87ldbr21ju.fsf_-_@email.froward.int.ebiederm.org> (raw)
In-Reply-To: <877bnb4uyw.fsf_-_@email.froward.int.ebiederm.org> (Eric W. Biederman's message of "Fri, 03 Jul 2026 16:35:51 -0500")


The function audit_core_dumps is not about the coredumps but about
detecting the conditions that would trigger a coredump, and logging
something when that happens.  The function audit_core_dumps runs
even if a coredump never happens.

So move audit_core_dumps out of vfs_coredump and into get_signal
to make it clear it does not care about the actual core dumps.
