It looks like you used the patch command to apply Alexey's patch, which
will end up making you the author.
You'll need to use git to make Alexey the author or use git to import the
patch from Alexey. Then you would just have Alexey's signed off followed
by yours as you have below without having to specify the From: in the
commit message.
Thanks,
Tom
