raw_write_seqcount_begin(9)

✨ raw_write_seqcount_begin(9) ✨

okay bestie so this is a page straight out of the Kernel API Manual (yes, that manual, the big serious one) and we're talking about one single little function that kicks off a write section. slay. 🎀

---

💖 NAME 💖

raw_write_seqcount_begin — start a seqcount_t write section w/o lockdep

like, it opens the write side of the party and lockdep is NOT invited 💅

---

🦋 SYNOPSIS 🦋

raw_write_seqcount_begin (s );

that's it. one arg. she's lowkey minimal.

---

🌸 ARGUMENTS 🌸

• s — Pointer to seqcount_t or any of the seqcount_LOCKNAME_t variants. so like, whichever flavour of seqcount you're holding, hand her the pointer and she'll take it from there 🫶

---

⭐ CONTEXT ⭐

check write_seqcount_begin

(yep, that's the whole context note — she said what she said 😌)
