Subject: Re: [PATCH wq/for-7.4-fixes] workqueue: Fix drain_workqueue() missing work items chained across pwqs
Date: Mon, 02 Nov 2026 08:21:33 -1000 [thread overview]
Message-ID: <36ebbc359b76693fcbeecbfdbed5ca41@kernel.org> (raw)
In-Reply-To: <20261030164210.3735018-1-tj@kernel.org>
Applied to wq/for-7.4-fixes with the following tag added:
Reviewed-by: Breno Leitao <leitao@debian.org>
With this patch, a work item that keeps re-queueing itself forever
makes drain_workqueue() loop forever. The current code can escape that
through this race, but the escape still trips the WARN in
destroy_workqueue() and leaks the workqueue.
Thanks.
