I think for all the network storage stuff we really need a "send me
out a page helper", and the nvmet bits that Dave pointed to look to
me like they actually are currently broken.
Given that Dave doesn't want to change the kernel_sendpage semantics
I'll resend with a new helper instead. Any preferences for a name?
safe_sendpage? kernel_sendpage_safe? kernel_send_one_page?
