Subject: [PATCH for-next 2/7] io_uring: remove unnecessary variable
Date: Mon, 15 Aug 2022 06:09:06 -0700	[thread overview]
Message-ID: <20220815130911.988014-3-dylany@fb.com> (raw)
In-Reply-To: <20220815130911.988014-1-dylany@fb.com>

'running' is set once and read once, so can easily just remove it
