Subject: [PATCH net-next 0/2] netns: uevent performance tweaks

Hey,

This series deals with a bunch of performance improvements when sending out
uevents that have been extensively discussed here:
https://lkml.org/lkml/2018/4/10/592

- Only record uevent sockets from network namespaces owned by the
  initial user namespace in the global uevent socket list.
  Eric, this is the exact patch we agreed upon in
  https://lkml.org/lkml/2018/4/10/592.
  **A very detailed rationale is present in the commit message for
    [PATCH 1/2] netns: restrict uevents**
- Decouple the locking for network namespaces in the global uevent socket
  list from the locking for network namespaces not in the global uevent
  socket list.
  **A very detailed rationale is present in the commit message
    [PATCH 2/2] netns: isolate seqnums to use per-netns locks**

Thanks!
Christian
