# HEAD: 291da9d4a9eb3a1cb0610b7f4480f5b52b1825e7 locking/mutex: Fix non
debug version of mutex_lock_io_nested()
Fix the non-debug mutex_lock_io_nested() method to map to mutex_lock_io()
instead of mutex_lock().
Right now nothing uses this API explicitly, but this is an accident waiting to
happen.
Thanks,
Ingo
