It also allows us to extend cluster info to include stack flags. This patch also adds stackflags to sb->s_clusterinfo. It also introduces a clusterinfo flag OCFS2_CLUSTER_O2CB_GLOBAL_HEARTBEAT to denote the enabled global heartbeat mode. This incompat flag can be set/cleared using tunefs.ocfs2 --fs-features. The clusterinfo flag is set/cleared using tunefs.ocfs2 --update-cluster-stack. Signed-off-by: Sunil Mushran --- Reading git-diff-tree failed
