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?
