Subject: [PATCH RFC v2 11/16] coredump: s/startup/done/g
Date: Wed, 02 Sep 2026 17:58:29 +0200	[thread overview]
Message-ID: <20260902-work-coredump-unlock-self-v2-11-1bece368cbb1@kernel.org> (raw)
In-Reply-To: <20260902-work-coredump-unlock-self-v2-0-1bece368cbb1@kernel.org>

We're going to use that in a bit. Rename it to something easier to
understand.

No functional changes.
