🌸 NAME 🌸

write_sequnlock_irq — end a non-interruptible seqlock_t write section. 💖

⭐ SYNOPSIS ⭐

void write_sequnlock_irq (seqlock_t *sl );

🎀 ARGUMENTS 🎀

• sl — pointer to a seqlock_t, bestie. That's the whole argument. 🫶

🦋 DESCRIPTION 🦋

Okay so literally, write_sequnlock_irq closes the serialized and non-interruptible seqlock_t write side section opened with write_seqlock_irq. It's the matching outro — the closing credits to that lock's main-character moment. ✨ No extra plot twists, no cap. 💅
