Thanks to Mark Hlawatschek for pointing this out.

ce3a68d817 Make clvmd-cman use a hash rather than an array for node updown info. 
This will allow it to cope with very large nodeids such as those
generated by clusters using cman_tool join -X

9154a74400 . remove_lock_wait.diff remove the definition of "struct lock_wait", 
which is not used since the switch away from async version saLck
. num_nodes should equal to member_list_entries, i.e.
joined_list_entires is 0 when a node leaves the group.

Thanks to Xinwei Hu for the patch.

1399b84b32 The attached patch is a try to make clvmd work correctly on openais stack. 
It does 2 things.

1. The cpg_deliver_callback make a compare between target_nodeid and our_nodeid.
It turns out openais set target_nodeid to 0 sometimes. for broadcasting ? I change the behavior so that lvm will process_remote also on target_nodeid == 0

2. The joined_list passed to cpg_confchg_callback doesn't include the already exist nodes in the group, which leads to an incomplete node_hash. I simply add all other nodes in member_list to node_hash also.

Thanks to Xinwei Hu for this patch.

49a552ccdc Add config file overrides to clvmd when it reads the LVs list so that 
config items 'command_names' and 'prefix' don't prevent it working.

e7bdd69af0 If lvm.conf was touched, clvmd attempted to update the toolcontext 
but only did half of the job. It now shares the do_refresh_cache()
function that vgscan invokes.
