"git am" says:
/home/blp/db/.git/rebase-apply/patch:163: trailing whitespace.
free_percpu(dp->stats_percpu);
warning: 1 line adds whitespace errors.
There's an existing instance of
vport_get_ifindex(get_vport_protected(dp, OVSP_LOCAL)) in
dp_fill_ifinfo(). I don't know whether you want to convert that one
to use get_dpifindex() or not. The existing call should always get an
ifindex, but then so should most of the calls to get_dpifindex().
