Subject: [PATCH net-next 0/3] netns: Optimise netns ID lookups

Netns ID lookups can be easily protected by RCU, rather than by holding
a spinlock.

Patch 1 prepares the code, patch 2 does the RCU conversion, and finally
patch 3 stops disabling BHs on updates (patch 2 makes that unnecessary).

Guillaume Nault (3):
  netns: Remove __peernet2id_alloc()
  netns: protect netns ID lookups with RCU
  netns: don't disable BHs when locking "nsid_lock"
