Subject: [Qemu-devel] [PATCH 0/2] block: support drive_del with dataplane
Date: Mon, 18 Aug 2014 16:07:11 +0100 [thread overview]
Message-ID: <1408374433-5360-1-git-send-email-stefanha@redhat.com> (raw)
This series makes hot unplug work with virtio-blk dataplane devices. It should
also work with Fam's virtio-scsi dataplane patches.
Up until now dataplane installed an op blocker that prevented drive_del.
Thanks to the op blocker and AioContext acquire/release infrastructure we can
now make drive_del safe.
Stefan Hajnoczi (2):
block: acquire AioContext in do_drive_del()
virtio-blk: allow drive_del with dataplane
