Subject: [PATCH v2 02/15] qapi/block-core: add option for io_uring
Date: Fri, 25 Oct 2019 18:04:31 +0200 [thread overview]
Message-ID: <20191025160444.31632-3-stefanha@redhat.com> (raw)
In-Reply-To: <20191025160444.31632-1-stefanha@redhat.com>
From: Aarushi Mehta <mehta.aaru20@gmail.com>
Only enumerates option for devices that support it. Since QAPI schema
supports io_uring, which is the actual name of the Linux API, it is
preferred over io-uring.
