Subject[PATCH v1 net 00/15] sysctl: Fix data-races around net.core.XXX (Round 1)
Date
This series fixes data-races around 22 knobs in net_core_table.
These knobs are skipped:

- netdev_rss_key: Written only once by net_get_random_once() and
read-only knob
- rps_sock_flow_entries: Protected with sock_flow_mutex
- flow_limit_cpu_bitmap: Protected with flow_limit_update_mutex
- flow_limit_table_len: Protected with flow_limit_update_mutex
- default_qdisc: Protected with qdisc_mod_lock
- warnings: Unused

Note 9th patch fixes net.core.message_cost and net.core.message_burst,
and lib/ratelimit.c does not have an explicit maintainer.

The next round is the final round for net.core.XXX and starts from
netdev_budget_usecs.
