I'm definitively not an expert on RCU, so the more reviews we can get the better. To the best of my (limited) knowledge, the code looks reasonable. > docs: Add mshv to documentation > MAINTAINERS: Add maintainers for mshv accelerator > The rest looks okay. > Praveen K Paladugu (1): > qapi/accel: Allow to query mshv capabilities > This looks problematic and probably needs to be changed. I really hope that we can commit as many patches as possible to QEMU tree, so that we don't need to keep rebasing. Thanks, Wei
