From 0c7294ddae73ad8d7532f95a86259e311e991a55 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Fri, 19 Jul 2019 18:20:14 +0200 Subject: [PATCH] net: flow_offload: remove netns parameter from flow_block_cb_alloc() No need to annotate the netns on the flow block callback object, flow_block_cb_is_busy() already checks for used blocks. Fixes: d63db30c8537 ("net: flow_offload: add flow_block_cb_alloc() and flow_block_cb_free()") Signed-off-by: Pablo Neira Ayuso Acked-by: Jiri Pirko Signed-off-by: David S.
