write_sequnlock_irqrestore(9)

💖 write_sequnlock_irqrestore(9) 💖

hiii bestie, welcome to the Kernel API Manual page for write_sequnlock_irqrestore(9) — yes, the seqlock cleanup girlie is here to close things out properly. ✨

---

🌸 NAME 🌸

write_sequnlock_irqrestore — end a non-interruptible seqlock_t write section. That’s the whole vibe: it’s the closing move. 💅

---

✨ SYNOPSIS ✨

void write_sequnlock_irqrestore (seqlock_t *sl , unsigned long flags );

---

🎀 ARGUMENTS 🎀

• sl — Pointer to seqlock_t. That’s your seqlock bestie. 🫶
• flags — Caller’s saved interrupt state, from write_seqlock_irqsave. Keep those flags safe, okay? 😭

---

💅 DESCRIPTION 💅

okay so write_sequnlock_irqrestore closes the serialized and non-interruptible seqlock_t write section that was previously opened with write_seqlock_irqsave. It’s literally the matching close-out step — section opened, section closed, no cap. 🔥
