The series introduces fine grained rw_semaphore, which will be used
instead of rtnl_lock() to protect net_namespace_list.
This improves scalability and allows to do non-exclusive sleepable
iteration for_each_net(), which is enough for most cases.
scripts/get_maintainer.pl gives enormous list of people, and I add
all to CC.
Note, that this patch is independent of "Close race between
{un, }register_netdevice_notifier and pernet_operations":
