[Samba] using splice system call in smbd

[saeed bishara]

Hi,
   Linux kernel 2.6.17 introduced new system calls, the splice() and
tee(), see http://kerneltrap.org/node/6505. using those system calls
supposed to eliminate the copy_to/from_user in when writing files, the
same way the sendfile does for reads. so is there any body how tried
to use those functions in samba server?
