Subject: [patch net-next v2 02/20] net: sched: use extended variants of block_get/put in ingress and clsact qdiscs
Date: Thu, 19 Oct 2017 15:50:30 +0200 [thread overview]
Message-ID: <20171019135048.4306-3-jiri@resnulli.us> (raw)
In-Reply-To: <20171019135048.4306-1-jiri@resnulli.us>
From: Jiri Pirko <jiri@mellanox.com>
Use previously introduced extended variants of block get and put
functions. This allows to specify a binder types specific to clsact
ingress/egress which is useful for drivers to distinguish who actually
got the block.
