Gang He 382896281b ocfs2: remove ocfs2_is_o2cb_active() ... commit a634644751c46238df58bbfe992e30c1668388db upstream. Remove ocfs2_is_o2cb_active(). We have similar functions to identify which cluster stack is being used via osb->osb_cluster_stack. Secondly, the current implementation of ocfs2_is_o2cb_active() is not totally safe. Based on the design of stackglue, we need to get ocfs2_stack_lock before using ocfs2_stack related data structures, and that active_stack pointer can be NULL in the case of mount failure.
