💅 handle_early...ue_pi_wakeup(9) 💅

okay bestie, welcome to the Kernel API Manual — we're talking about handle_early_requeue_pi_wakeup, and yes the page header is literally truncated like handle_early...ue_pi_wakeup(9) (iykyk 😭).

✨ NAME ✨

handle_early_requeue_pi_wakeup — Handle early wakeup on the initial futex. no cap, that's the whole vibe: it handles an early wakeup on the initial futex 🫶

🌸 SYNOPSIS 🌸

Here's the signature, bestie — copy it exactly, do not freestyle the types:

int handle_early_requeue_pi_wakeup (struct futex_hash_bucket *hb , struct futex_q *q , struct hrtimer_sleeper *timeout );

🎀 ARGUMENTS 🎀

• hb — the hash_bucket that futex_q was original enqueued on. yes, “original” is the manpage's word, we're not fixing it 💀
• q — the futex_q woken while waiting to be requeued. like it literally got woken up while waiting to be requeued 😭
• timeout — the timeout associated with the wait, or NULL if there's none. no timer, no drama.

🦋 DESCRIPTION 🦋

Determine the cause for the early wakeup. that's it, that's the mission. figure out why this thing woke up early — main character investigation energy 🔍✨

🔥 RETURN 🔥

It returns one of these bad boys, fr fr:

• -EWOULDBLOCK
• -ETIMEDOUT
• -ERESTARTNOINTR
