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!
