Subject: Re: [RFC PATCH v3 01/11] KEYS: Add key_gc_flush() for draining RCU callbacks
Date: Fri, 06 Nov 2026 00:54:02 +0000 [thread overview]
Message-ID: <sashiko-outbox-200456@kernel.org> (raw)
In-Reply-To: <20261105005311.804098-2-jarkko@kernel.org>
> keyring_clear() and key_invalidate() release keyring links via call_rcu(),
> and key_put() defers final key destruction to key_gc_work.
>
> Once keys pin their type, callers that clear an internal cache before
> module unload need a synchronous barrier so module references can be
> dropped before delete_module() checks the refcount.
>
> Add key_gc_flush() for flushing the remaining key_gc_work passes.
