Subject: [PATCH 0/4] Improve virtio ID allocation
Date: Wed, 26 Sep 2018 09:00:27 -0700 [thread overview]
Message-ID: <20180926160031.15721-1-willy@infradead.org> (raw)
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
