So consider them as Reviewed-by me but not necessary to add the tag in commit, Reviewed-by: loic in commit is sufficient. Concerning tests, it works find except the crash recovery from a sync start. But i suppose that you know the limitation, waiting Loic patches[1] update :) [1]: https://lkml.org/lkml/2020/3/11/403 Thanks a lot for your work!
