hi,brassow,
How is going about the userspace cmirrord's patch testing? Is there anything I could help?

hi, brassow

Yes, I had submited a patch lvm-devel.

http://www.redhat.com/archives/lvm-devel/2013-November/msg00093.html.

please review.

I should have add a patch version indicator.

Looks good. Did you happen to post the accompanying userspace patches?
If you pass those along, I will review that also and test them
together. Once that's done, I will ACK.

Extra newline...

The rest looks good. (Cosmetic issues like this wouldn't prevent my
ACK though.)
