| |
This patch removes the following warning:
kernel/lockdep.c:580: warning: ‘print_lock_dependencies’ defined but not used
Now functions print_lock_dependencies and print_lock_class_header are now compiled only if both CONFIG_TRACE_IRQFLAGS and CONFIG_PROVE_LOCKING are defined; function lockdep_dependency_visit and variable lockdep_dependency_gen_id are compiled only if CONFIG_PROVE_LOCKING is defined
