[Ocfs2-devel] [PATCH] Use dlm_print_one_lock_resource for lock reason.

[Tao Ma]

__dlm_print_one_lock_resource must be called with spin_lock
the res->spinlock. While in some cases, we use it without this
precondition and lead to the failure of assert_spin_locked.
So call dlm_print_one_lock_resource instead.
