From: Mark Fasheh Date: Mon, 24 Sep 2007 22:09:41 +0000 (-0700) Subject: ocfs2: Remove fs dependency on ocfs2_heartbeat module X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6f7b056ea9c6fa978c79ca626eff43549df94dbb;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git ocfs2: Remove fs dependency on ocfs2_heartbeat module Now that the dlm exposes domain information to us, we don't need generic node up / node down callbacks. And since the DLM is only telling us when a node goes down unexpectedly, we no longer need to optimize away node down callbacks via the umount map.
