Subject: [PATCH for-next v3 05/16] io_uring: poll: remove unnecessary req->ref set
Date: Thu, 16 Jun 2022 10:22:01 +0100 [thread overview]
Message-ID: <ec6fee45705890bdb968b0c175519242753c0215.1655371007.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
From: Hao Xu <[email protected]>
We now don't need to set req->refcount for poll requests since the
reworked poll code ensures no request release race.
