Subject: [RESEND PATCH v2 2/7] block: remove redundant mq check
Date: Thu, 8 Oct 2020 23:26:28 -0400 [thread overview]
Message-ID: <20201009032633.83645-3-yuyufen@huawei.com> (raw)
In-Reply-To: <20201009032633.83645-1-yuyufen@huawei.com>
elv_support_iosched() will check queue_is_mq() for us. So, remove
the redundant check to clean code.
