[Qemu-devel] [PATCH v2 0/8] virtio: enhance virtio_error messages

[Ladi Prosek <lprosek@redhat.com>]

Output like "Virtqueue size exceeded" is not much useful in identifying the
culprit. This series beefs up virtio_error to print the virtio device name
and id, and introduces virtqueue_error which additionally includes the index
of the virtqueue where the error occured.

Patches 1 to 3 lay the groundwork, patches 4 to 8 convert virtio devices to
use virtqueue_error instead of virtio_error.

v1->v2:
* Modified virtio_error and added virtqueue_error (Stefan)
* Now also printing device id (Stefan)
* Went over all virtio_error call sites and converted them to virtqueue_error
  as appropriate; added virtio device maintainers to cc

Ladi Prosek (8):
  qemu-error: introduce error_report_nolf
  virtio: enhance virtio_error messages
  virtio: introduce virtqueue_error
  virtio-9p: use virtqueue_error for errors with queue context
  virtio-blk: use virtqueue_error for errors with queue context
  virtio-net: use virtqueue_error for errors with queue context
  virtio-scsi: use virtqueue_error for errors with queue context
  virtio-crypto: use virtqueue_error for errors with queue context
