Hi,

this patch should be v4.
You re-sent it with a modified commit message (the position of your S-o-b)

The idea behind patch versions is to help maintainer. With the way you 
did, now 2 patches stating v3 are available.
Which one is the correct one?
The maintainer would need to look at both, search for differences, maybe 
look at the date of the mails.
A v4 would be much easier for him.


Also, when you send an updated version of a patch, it should always be 
"complete". I mean that the patch below seems to need v2, and maybe even 
v1 (which is apparently not on the linux-kernel mailing list).

A maintainer can't know by himself what is needed and what is not.

So you should resend a new patch.
It should be a v4, and it should include what is needed from (v1?), v2 
and v3 all together.
