[PATCH 0/2] kobject: reduce uevent_sock_mutex contention

[Eric Dumazet]

This series reduces the (small ?) contention over uevent_sock_mutex,
noticed when creating/deleting many network namespaces/devices.

1) uevent_seqnum becomes an atomic64_t

2) Only acquire uevent_sock_mutex whenever using uevent_sock_list

Eric Dumazet (2):
  kobject: make uevent_seqnum atomic
  kobject: reduce uevent_sock_mutex scope
