How hard would it be to add the UIO_NOCOPY functionality in smbfs?
This is required for sendfile(2) to work
in /usr/src/sys/vfs/smbfs/smbfs_io.c on line 183 this exists:
* Protect against method which is not supported for now
if (uiop->uio_segflg == UIO_NOCOPY)
EOPNOTSUPP is also the error that sendfile returns.
If it's not too hard, I might give it a try as a newbeginner kernel
hacker, given the right directions...
I've seen this error reported on various places since this problem
aslo exists in freebsd
