From aeb3fecde811d5392ed481d8558f5751ac542e77 Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Tue, 11 Dec 2018 11:15:46 -0800 Subject: [PATCH] net_sched: fold tcf_block_cb_call() into tc_setup_cb_call() After commit 69bd48404f25 ("net/sched: Remove egdev mechanism"), tc_setup_cb_call() is nearly identical to tcf_block_cb_call(), so we can just fold tcf_block_cb_call() into tc_setup_cb_call() and remove its unused parameter 'exts'.
