QUEUE_ME(9) Futex API reference QUEUE_ME(9)

NAME

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

struct futex_q * q
The futex_q to enqueue

struct futex_hash_bucket * 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).
