From: Goldwyn Rodrigues Date: Sat, 29 Mar 2014 15:20:02 +0000 (-0500) Subject: Introduce md_cluster_info X-Git-Tag: omap-for-v4.1/fixes-rc1~34^2~21^2~31 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c4ce867fdad200dfd8aa8cbe1eabc26c14c51635;p=pandora-kernel.git Introduce md_cluster_info md_cluster_info stores the cluster information in the MD device. The join() is called when mddev detects it is a clustered device. The main responsibilities are: 1. Setup a DLM lockspace 2. Setup all initial locks such as super block locks and bitmap lock (will come later) The leave() clears up the lockspace and all the locks held.
