From 7902a391683eabe46bdc75d0b182484702c5b9b1 Mon Sep 17 00:00:00 2001 From: Pravin B Shelar Date: Tue, 23 Apr 2013 07:48:48 +0000 Subject: [PATCH] openvswitch: Use parallel_ops genl. OVS locking was recently changed to have private OVS lock which simplified overall locking. Therefore there is no need to have another global genl lock to protect OVS data structures. Following patch uses of parallel_ops genl family for OVS. This also allows more granual OVS locking using ovs_mutex for protecting OVS data structures, which gives more concurrencey. E.g multiple genl operations OVS_PACKET_CMD_EXECUTE can run in parallel, etc. Signed-off-by: Pravin B Shelar Signed-off-by: David S.
