Subject: [PATCH 5/7] io_uring: remove extra ->file check in poll prep
Date: Sun, 18 Oct 2020 10:17:41 +0100	[thread overview]
Message-ID: <d2a569f6dbbdd7bf2e497bdffe642f0731fee6c2.1603011899.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

io_poll_add_prep() doesn't need to verify ->file because it's already
done in io_init_req().
