Thanks, this looks good to me and passes my testing (on tcp).

+typedef struct bio_vec lnet_kiov_t;

This I guess we'll need to just get rid of all lnet_kiov_t usage, but that's
something we can do ourselves, I guess.

Anyway, your patchset is based on old tree that no longer applies cleanly,
I rebased it to current staging tree to save you time in case
you want to go forward with it.
It's at git@github.com:verygreen/linux.git branch lustre-next-sendmsg

James, can you please give it a try on IB?

Bye,
Oleg
