[PATCH v2 net-next 0/3] net sched action timestamp improvements

[Jamal Hadi Salim]

From: Jamal Hadi Salim <jhs@mojatatu.com>

Various aggregations of duplicated code, fixes and introduction of firstused
timestamp

v2: add const for source time info per suggestion from Cong

Jamal Hadi Salim (3):
  net sched: actions use tcf_lastuse_update for consistency
  net sched actions: introduce timestamp for firsttime use
  net sched actions: aggregate dumping of actions timeinfo

[PATCH v2 net-next 2/3] net sched actions: introduce timestamp for firsttime use

[Jamal Hadi Salim]

From: Jamal Hadi Salim <jhs@mojatatu.com>

Useful to know when the action was first used for accounting
