Merge tag 'locking-urgent-2021-03-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking fix from Ingo Molnar: "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" * tag 'locking-urgent-2021-03-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: locking/mutex: Fix non debug version of mutex_lock_io_nested()
