From 840a185dddfd098b78b96a30da4cad722a7aef18 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 29 Oct 2010 01:15:29 +0000 Subject: aoe: remove dev_base_lock use from aoecmd_cfg_pkts() dev_base_lock is the legacy way to lock the device list, and is planned to disappear. (writers hold RTNL, readers hold RCU lock) Convert aoecmd_cfg_pkts() to RCU locking. Signed-off-by: Eric Dumazet Cc: "Ed L. Cashin" Signed-off-by: David S.
