Not that I am fan of this but it will sync the symbols with what landed upstream as of commit f8635d509d807 ("locking/ww_mutex: Implement rtmutex based ww_mutex API functions") therefore it would be good to have.

We can use EXPORT_SYMBOL() instead of EXPORT_SYMBOL_GPL() in ww_mutex_lock_interruptible() and ww_mutex_lock(). That match ww_mutex_unlock() well. And also good for 3rd kernel modules.
