Hi Michal, I think I make a mistake by not adding you into the mail receiver list since you are the reviewer of V1, and these patches have been submitted for more than two weeks. The v2 patches locates in this link: https://www.redhat.com/archives/libvir-list/2019-June/thread.html#00288 I wonder if you have time to have a review. Actually I aimed to submit the MBM patches, Which is ready based on these patches, and this series of patches for cleanups and fixes to existing codes to make the upcoming MBM patches to be more reasonable. If you think it is necessary to review the MBM patches as a whole , I can send them out shortly.
