Subject: [PATCH net-next,v4 06/12] net: flow_offload: add flow_block_cb_{priv,incref,decref}()
Date: Tue, 9 Jul 2019 22:55:44 +0200 [thread overview]
Message-ID: <20190709205550.3160-7-pablo@netfilter.org> (raw)
In-Reply-To: <20190709205550.3160-1-pablo@netfilter.org>
This patch completes the flow block API to introduce:
* flow_block_cb_priv() to access callback private data.
* flow_block_cb_incref() to bump reference counter on this flow block.
* flow_block_cb_decref() to decrement the reference counter.
These functions are taken from the existing tcf_block_cb_priv(),
tcf_block_cb_incref() and tcf_block_cb_decref().
