queue_me (9) Linux Manual Page
queue_me – Enqueue the futex_q on the futex_hash_bucket
Synopsis
void queue_me(struct futex_q *q, struct futex_hash_bucket *hb);Arguments
q
-
- The futex_q to enqueue
hb
- The destination hash bucket
Description
The hb->lock must be held by the caller, and is released here. A call to queue_me is typically paired with exactly one call to unqueue_me. The exceptions involve the PI related operations, which may use unqueue_me_pi or nothing if the unqueue is done as part of the wake process and the unqueue state is implicit in the state of woken task (see futex_wait_requeue_pi for an example).
