Hi!

Seems like something funny is going on with get_maintainer.pl since XDP
entry got added.  We seem to have been CCed on:

net: ns83820: code cleanup for ns83820_probe_phy()
veth: Fix -Wformat-truncation
INFO: task hung in rtnetlink_rcv_msg

I tried Florian's veth patch myself and it does indeed produce:

"David S. Miller" <davem@davemloft.net> (odd fixer:NETWORKING DRIVERS,commit_signer:9/15=60%)

linux-kernel@vger.kernel.org (open list)
xdp-newbies@vger.kernel.org (open list:XDP (eXpress Data Path))

Even though it only touches:

 drivers/net/veth.c | 3 ++-
 1 file changed, 2 insertions(+), 1 deletion(-)

And XDP entry is:

So no relation to drivers at all...
