Subject: [PULL v2 15/17] docs: add 'io_uring' option to 'aio' param in qemu-options.hx
Date: Mon, 5 Oct 2020 16:43:21 +0100 [thread overview]
Message-ID: <20201005154323.31347-16-stefanha@redhat.com> (raw)
In-Reply-To: <20201005154323.31347-1-stefanha@redhat.com>
From: Stefano Garzarella <sgarzare@redhat.com>
When we added io_uring AIO engine, we forgot to update qemu-options.hx,
so qemu(1) man page and qemu help were outdated.
