[Ocfs2-devel] [PATCH] ocfs2_dlm: add spinlock protection before __dlm_print_one_lock_resource is called

[wengang wang]

ocfs2_dlm:  add spinlock protection per __dlm_print_one_lock_resource 
calling

In dlm_convert_lock_handler(), in case of !lock, 
__dlm_print_one_lock_resource is called. __dlm_print_one_lock_resource 
needs protection of spinlock on res->spinlock.  current source lost that 
protection.
use dlm_print_one_lock_resource instead of __dlm_print_one_lock_resource.
