Message-Id: <20180819192213.14196-3-xiyou.wangcong@gmail.com>
Date: Sun, 19 Aug 2018 12:22:06 -0700
From: Cong Wang <xiyou.wangcong@...il.com>
To: netdev@...r.kernel.org

Subject: [Patch net 2/9] net_sched: remove unnecessary ops->delete()
All ops->delete() wants is getting the tn->idrinfo, but we already
have tc_action before calling ops->delete(), and tc_action has
a pointer ->idrinfo.
More importantly, each type of action does the same thing, that is,
just calling tcf_idr_delete_index().
So it can be just removed.
Fixes: b409074e6693 ("net: sched: add 'delete' function to action ops")
