From 456ad75c89cdb72e11dcdb6b0794802a6f50c8a3 Mon Sep 17 00:00:00 2001 From: Denis Cheng Date: Wed, 18 Jul 2007 02:10:54 -0700 Subject: [NET]: move dev_mc_discard from dev_mcast.c to dev.c Because this function is only called by unregister_netdevice, this moving could make this non-global function static, and also remove its declaration in netdevice.h; Any further, function __dev_addr_discard is also just called by dev_mc_discard and dev_unicast_discard, keeping this two functions both in one c file could make __dev_addr_discard also static and remove its declaration in netdevice.h; Futhermore, the sequential call to dev_unicast_discard and then dev_mc_discard in unregister_netdevice have a similar mechanism that: (netif_tx_lock_bh / __dev_addr_discard / netif_tx_unlock_bh), they should merged into one to eliminate duplicates in acquiring and releasing the dev->_xmit_lock, this would be done in my following patch.
