[PATCH 0/4] Improve virtio ID allocation

I noticed you were using IDRs where you could be using the more efficient
IDAs, then while fixing that I noticed the lack of error handling,
and I decided to follow that up with an efficiency improvement.

There's probably a v2 of this to follow because I couldn't figure
out how to properly handle one of the error cases ... see the comment
embedded in one of the patches.

Matthew Wilcox (4):
  drm/virtio: Replace IDRs with IDAs
  drm/virtio: Handle context ID allocation errors
  drm/virtio: Handle object ID allocation errors
  drm/virtio: Use IDAs more efficiently
