seqcount_init(9)

💅 seqcount_init(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual page for seqcount_init(9) — yes that's the manual name, yes it's giving "I live in man 9" energy, and yes we're gonna get through it together 🫶

---

✨ NAME ✨

seqcount_init — the runtime initializer for seqcount_t. that's it. that's the whole vibe. she initializes at runtime, no cap 💅

---

🌸 SYNOPSIS 🌸

seqcount_init (s );

literally that's the call. short, iconic, done 👑

---

🎀 ARGUMENTS 🎀

• s — pointer to the seqcount_t instance. like, you hand her the address of your lil seqcount and she does her thing. a pointer. to a seqcount_t. that's the whole argument, bestie 💖

---

🦋 SEE ALSO 🦋

okay this is the part where the manpage goes feral and lists everything, and honestly? obsessed. she's citing the whole friend group 💀 the whole thing lives in the kernel file ./include/linux/seqlock.h, and here's every single sibling:

ngl bestie, this page is short because the function is short — don't go inventing extra behavior for her, she's just the runtime initializer 💜

---

and that's the whole page, bestie!! 🎀 cute lil sign-off: this one comes from ./include/linux and it's dated October 2026 — so yes, she's from the future and she's still just initializing seqcounts 💅✨ periodt 🦋
