Subject: Re: [PATCH v5 03/12] NFSv4: Clear idmap keyring cache when the last client unloads
Date: Mon, 09 Nov 2026 22:28:25 +0000 [thread overview]
Message-ID: <sashiko-outbox-205729@kernel.org> (raw)
In-Reply-To: <20261108222719.304712-4-jarkko@kernel.org>
> id_resolver_cache->thread_keyring caches id_resolver_legacy keys up until
> nfs_idmap_quit() tears down the keyring.
>
> Once keys pin to the kernel module of their key type, the cached keys
> prevent module_exit() from ever happening.
>
> Track the active idmap instances under a mutex and clear the idmap cache
> keyring once the last client has been destroyed.
