I tried `base-commit: 962ac5ca99a5c3e7469215bf47572440402dfd59` as mentioned in the cover, but didn't apply. After several tries I successfully applied on top of commit bc69ed975203 ("Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost") So, I agree, better to resend and you can remove RFC. BTW I'll do my best to start to review tomorrow! Thanks, Stefano
