Linux version 3.1 introduced a consistency check for netlink dumps in
commit 670dc28 ("netlink: advertise incomplete dumps"). This bites
iproute2 when flushing more addresses than can fit into a single
RTM_GETADDR response. To silence the spurious error message "Dump was
interrupted and may be inconsistent.", advise rtnl_dump_filter_l() to
not care about NLM_F_DUMP_INTR.

    The scripts/checkpatch.pl now enforces 12-digit commit ID...

    Sorry, didn't realize it wasn't a kernel patch. :-)

Heh, no problem! If more projects used checkpatch.pl, the world would be
a better place.

My quoting commits was usually a matter of copying what 'git --oneline
show' outputs. Thanks for the heads-up, I've adjusted core.abbrev now.

Cheers, Phil
