Grrrr. It seems that slice() is broken
on at least kernel 2.6.22 (Ubuntu 7.10)
- it works as sendfile (file -> network)
but not as recvfile (network -> file).

I'll add in the configure test tomorrow
and can detect the failure and fall back
to the userspace implementation on error,
this will allow me to commit the code and
let systems with *working* implementations
(hi there FreeBSD :-) to add in their versions
and send me the patches for 3.2.x.

I need this to enable the 16Mb direct writes
for the CIFSFS and MacOS clients.

F*%king Linux strikes again..... :-(.

A HALF IMPLEMENTED FEATURE IS NOT A KERNEL
FEATURE YOU CAN ANNOUNCE !!!!!
