From 828ae6afbef03bfe107a4a8cc38798419d6a2765 Mon Sep 17 00:00:00 2001 From: Andrew Beekhof Date: Mon, 4 Dec 2006 14:04:55 +0100 Subject: [patch 3/3] OCFS2 Configurable timeouts - Protocol changes Modify the OCFS2 handshake to ensure essential timeouts are configured identically on all nodes. Only allow changes when there are no connected peers Improves the logic in o2net_advance_rx() which broke now that sizeof(struct o2net_handshake) is greater than sizeof(struct o2net_msg) Included is the field for userspace-heartbeat timeout to avoid the need for further protocol changes. Uses a global spinlock to ensure the decisions to update configfs entries are made on the correct value. The region covered by the spinlock when incrementing the counter is much larger as this is the more critical case.
