Subject: [Qemu-devel] [PATCH 0/2] virtio-blk: Switch to blk_aio_ioctl
Date: Tue, 20 Jan 2015 11:28:45 +0800 [thread overview]
Message-ID: <1421724527-24557-1-git-send-email-famz@redhat.com> (raw)
There are user complaints on guest's unresponsiveness when ioctl is blocked due
to the lost connection to backend or other issues. This series changes scsi
request processing of virtio-blk to an asynchronous manner.
Fam Zheng (2):
virtio-blk: Pass req to virtio_blk_handle_scsi_req
virtio-blk: Use blk_aio_ioctl
