Hi, He

0day robot has't applied previous 0001 and 0002 patches in this case
for it considered this patch as an individual one. Please ignore this
warning. 

Btw: You could try use git(>=2.9.0) format-patch --base=<commit> (or
--base=auto for convenience) to record what (public, well-known) commit
your patch series was built on.

Thanks,
Xiaolong
