locking/mutex: Fix non debug version of mutex_lock_io_nested()
commit 291da9d4 upstream. If CONFIG_DEBUG_LOCK_ALLOC=n then mutex_lock_io_nested() maps to mutex_lock() which is clearly wrong because mutex_lock() lacks the io_schedule_prepare()/finish() invocations. Map it to mutex_lock_io(). Fixes: f21860ba ("locking/mutex, sched/wait: Fix the mutex_lock_io_nested() define") Signed-off-by:Thomas Gleixner <tglx@linutronix.de> Signed-off-by:
