[PATCH 00/14] Modify action API for implementing lockless actions

Currently, all netlink protocol handlers for updating rules, actions and qdiscs are protected with single global rtnl lock which removes any possibility for parallelism. This patch set is a first step to remove rtnl lock dependency from TC rules update path. It updates act API to use atomic

[PATCH] lib/rhashtable: reorder some inititalization sequences

rhashtable_init() allocates memory at the very end of the call, once everything is setup; with the exception of the nelems parameter. However, unless the user is doing something bogus with params for which -EINVAL is returned, memory allocation is the only operation that can trigger the call to

[PATCH 14/14] net: sched: implement delete for all actions
