Cong Wang says:

====================
net_sched: act: more cleanup and improvement

v2 -> v3:
* fix a mis-splitted patch
* keep hinfo as a pointer in ops

v1 -> v2:
* Fix a bug noticed by Jamal
* Drop patches already merged into net-next
* Add patch 5/5

Patches are cleanup's for the structures of tc actions, except patch 4
which is an improvement.

See each patch for details.
