Subject: [patch v2 0/3] block: optimize flush for non-queueable flush drive
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

Flush request isn't queueable. When it's running, other request
can't. We can optimize flush performance according to this knowledge
In my test, I got about 20% performance boost.
