queue_me — Enqueue the futex_q on the futex_hash_bucket
void queue_me ( | struct futex_q * q, |
struct futex_hash_bucket * hb); |
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).
