When using sendfile() on an amd64 box, are sfbufs still used/needed? The reason I ask:

# netstat -m
0/0/0 sfbufs in use (current/peak/max)
0 requests for sfbufs denied
0 requests for sfbufs delayed
1334122 requests for I/O initiated by sendfile

kern.ipc.nsfbufsused: 0
kern.ipc.nsfbufspeak: 0
kern.ipc.nsfbufs: 0


Does sendfile work differently on amd64 so that sfbufs aren't needed, or is this a statistics issue?

This is in 7.0-RELEASE, btw.
