Since this patch seems to be backported from upstream, its description should 
contain a reference to upstream. In this case saying something like "upstream 
commit 6740579367d" should be enough.

Sorry for not mentioning it previously.

Thanks, applied after doing a few changes:

[Thomas:
  - indicate upstream commit id, as suggested by Baruch.
  - add SoB of Alexey inside the patch itself.
  - adjust sequence number to 0003.]
