Subject: [PATCH net-next 0/3] netns: Optimise netns ID lookups
Date: Mon, 13 Jan 2020 22:39:19 +0100 [thread overview]
Message-ID: <cover.1578950227.git.gnault@redhat.com> (raw)
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"
