Subject: [PATCH 22/23] io_uring: remove extra argument for overflow flush
Date: Thu, 29 Jul 2021 16:05:49 +0100	[thread overview]
Message-ID: <e15b092701c86cbcb0f41e7be11261c9744890f1.1627570633.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1627570633.git.asml.silence@gmail.com>

Unlike __io_cqring_overflow_flush(), nobody does forced flushing with
io_cqring_overflow_flush(), so removed the argument from it.
