After commit 098a697b ("tcp_metrics: Use a single hash table for all network namespaces.") we can avoid calling tcp_net_metrics_init() for each new netns. Instead, rename tcp_net_metrics_init() to tcp_metrics_hash_alloc(), and move it to __init section. Also move tcpmhash_entries to __initdata section. Signed-off-by:

Jiri Pirko says: ==================== devlink: use spec to generate split ops This is an outcome of the discussion in the following thread: https://lore.kernel.org/netdev/20230720121829.566974-1-jiri@resnulli.us/ It serves as a dependency on the linked selector patchset. There is an existing spec for devlink used for userspace part generation. There are two commands supported there. This patchset extends the spec so kernel split ops code could be generated from it. ==================== Link: https://lore.kernel.org/r/20230803111340.1074067-1-jiri@resnulli.us Signed-off-by:
