From 67bd0d5ea7974d9dc9c502c7b4096e16a80a553d Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Tue, 9 Jul 2019 22:55:44 +0200 Subject: [PATCH] net: flow_offload: add flow_block_cb_{priv, incref, decref}() 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(). Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S.
