snd_pcm_stre...k_irqrestore(9)

💅 snd_pcm_stre...k_irqrestore(9) 💅

okay bestie, welcome to the Kernel API Manual — yes, the actual kernel manual, we're doing this, and honestly? we're gonna slay it 🎀

---

✨ NAME ✨

snd_pcm_stream_unlock_irqrestore — the one that unlocks the PCM stream 🔓🦋

---

🌸 SYNOPSIS 🌸

void snd_pcm_stream_unlock_irqrestore (struct snd_pcm_substream
*substream , unsigned long flags );

like literally that's the whole signature, no cap 💅

---

🧚 ARGUMENTS 🧚

• substream — the PCM substream, aka the main character of this whole situation 👑
• flags — the irq flags, keep them safe, keep them close 🫶

---

🔥 DESCRIPTION 🔥

So this function is the counter-part of snd_pcm_stream_lock_irqsave — like, they're a matching set, they come as a pair, you literally cannot separate them, it's giving soulmate energy 💖✨

Translation for the girlies: one locks the stream (and saves the irq flags), and this one unlocks it and restores the flags. periodt. 🌈

ngl the manpage name got truncated to snd_pcm_stre...k_irqrestore(9) and honestly it's giving "my username was taken" energy 😭 but the vibes are immaculate regardless 🙈
