I reviewed the series, and made some tests on my side.
FYI, I do not answer to patches when tagged "Reviewed-by: Loic Pallardy" 
and with no extra remark. 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 :)

Thanks a lot for your work!
