seqcount_latch_init(9)

✨ NAME ✨

okay so this is seqcount_latch_init — from the Kernel API Manual, section 9, bestie — and it's literally the runtime initializer for seqcount_latch_t 💅 like it sets your latch seqcount up while the kernel is already running, no cap

🎀 SYNOPSIS 🎀

seqcount_latch_init (s );

that's the whole vibe, she's a one-liner 🦋

🌸 ARGUMENTS 🌸

• s — a pointer to the seqcount_latch_t instance, i.e. the actual latch seqcount you want initialized. gotta hand her the address of the thing, not the thing itself 🫶

👑 SEE ALSO 👑

the kernel file is ./include/linux/seqlock.h and honestly the whole seqlock girlie ecosystem lives there, so here's the full bestie list — every single one, no skipping 🔥

fr fr that's the entire squad, go read them all before you touch a latch, iykyk 💀

and that's the page, bestie 🌈 this one came out of the kernel source tree at ./include/linux, dated October 2026 — mwah, go init some latches responsibly 😭💖
