Just cc'ing is not enough. I was going to send my v2 for XFS/iomap 
support today. I didn't announce that as I did not think that I had to. 
Admittedly it will be effectively an RFC, as the forcealign feature (now 
included) is not mature. But it's going to be a bit awkward to have 2x 
overlapping series' sent to the list.

FWIW, I think that it's better to send series based on top of other 
series, rather than cherry-picking necessary parts of other series (when 
posting)

Thanks,
John
