From: Denys Vlasenko Date: Wed, 15 Jul 2015 12:56:05 +0000 (+0200) Subject: mac80211: deinline drv_sta_state X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=727da60be91c9fd59f1b084ca537b5123ab97744;p=openwrt%2Fstaging%2Fblogic.git mac80211: deinline drv_sta_state With this .config: http://busybox.net/~vda/kernel_config, after deinlining the function size is 3132 bytes and there are 7 callsites. Total size reduction: about 20 kbytes.
