It is good to see a rough draft of the manpage changes for an ABI 
addition like this before the patch gets merged just so we can catch 
anything odd about the interface.

Also include (as a comment) the git commit id that introduces the change.

In general manpage patches do not get committed until after the change
hits a full released kernel (as things have been known to get reverted 
from -rc kernels in the past).

If you send a rough patch I can fix it up and queue it up with other 
manpage patches I have (I'm a bit backlogged but working on catching up).
I'm never quite sure that I get all of the various Signed-off- lines right 
for contributed patches though.
