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(), ...
