From 42677ed33a8b6995e6af2ec15643840afcf1c48b Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Wed, 23 Sep 2015 14:18:34 +0200 Subject: mac80211: Deinline drv_switch_vif_chanctx() With this .config: http://busybox.net/~vda/kernel_config_ALLYES_Os, after deinlining the function size is 821 bytes and there are 2 callsites, reducing code size by about 800 bytes.
