Subject: [Qemu-devel] [PATCH 0/3] virtio-scsi: Fix unsafe bdrv_set_aio_context calls
Date: Thu, 12 Feb 2015 13:20:59 +0800 [thread overview]
Message-ID: <1423718462-25566-1-git-send-email-famz@redhat.com> (raw)
It is not safe to call bdrv_set_aio_context outside BQL (see patch 1), so move
the call to main thread (patch 3). And as a bonus, the two loops in
virtio-scsi.c and virtio-scsi-dataplane.c for cmd queue handling are converged
(patch 2).
Fam Zheng (3):
block: Forbid bdrv_set_aio_context outside BQL
virtio-scsi: Deduplicate cmd queue handling code of dataplane
virtio-scsi-dataplane: Use main thread BH to set BDS' aio context
