Subject: [PATCH net-next,v3 04/11] net: flow_offload: add flow_block_cb_alloc() and flow_block_cb_free()
Date: Mon, 8 Jul 2019 18:06:06 +0200 [thread overview]
Message-ID: <20190708160614.2226-5-pablo@netfilter.org> (raw)
In-Reply-To: <20190708160614.2226-1-pablo@netfilter.org>
Add a new helper function to allocate flow_block_cb objects.
Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
---
v3: instead of introducing tcf_block_cb_alloc() and tcf_block_cb_free()
to rename them later on in the series, add them upfront to flow_offload.c
to reduce the size of this batch.
