Linux Kernel v.5. linux/wait.h WAIT_QUEUE_HEAD

Is there any function like interruptible_sleep_on() in kernel v5? I found only poll_wait() for polling file.

In linux 3.5 source code, we can see that those functions were deprecated. Look at the comments above their declaration:

/*  
 * These are the old interfaces to sleep waiting for an event.  
 * They are racy.  DO NOT use them, use the wait_event* interfaces above.  
 * We plan to remove these interfaces.  
 */  
extern void sleep_on(wait_queue_head_t *q);  
extern long sleep_on_timeout(wait_queue_head_t *q,  
                      signed long timeout);  
extern void interruptible_sleep_on(wait_queue_head_t *q);  
extern long interruptible_sleep_on_timeout(wait_queue_head_t *q,  
                       signed long timeout);

The function to use instead are: wait_event_killable(), wait_event_timeout(), ...
