🌸 raw_atomic_long_fetch_andnot_release — Kernel API Manual ✨

okay bestie, welcome to the raw_atomic_l...dnot_release(9) page 💅 (yes the manual name is abbreviated like that, she's just being mysterious, iykyk). This is a Kernel API thing and it is literally SO specific. Let's go 🫶

---

🎀 NAME 🎀

raw_atomic_long_fetch_andnot_release — an atomic bitwise AND NOT with release ordering, no cap 🔥

---

✨ SYNOPSIS ✨

long raw_atomic_long_fetch_andnot_release (long i , atomic_long_t *v );

that's the whole vibe. two args. one long, one pointer. slay 💖

---

🌈 ARGUMENTS 🌈

• i — a long value. that's it, that's her job 🦋
• v — pointer to an atomic_long_t. this is the actual thing getting touched, be nice to her 🥺

---

👑 DESCRIPTION 👑

atomically updates v to (v & ~i) with release ordering 💫 so like, the AND NOT happens as one indivisible little moment, and the release ordering is baked in there too. main character behavior tbh.

also: it's safe to use in noinstr code — prefer atomic_long_fetch_andnot_release everywhere else though. noinstr is a whole special little club, don't just walk in there for fun 🙈

---

🧚 RETURN 🧚

the original value of v — like, before the update. she gives you the receipts of what she used to be, periodt 💀

ngl this page is short but she ate. bitwise AND NOT + release ordering + gives you the old value back = iconic behavior only 💅✨

that's the whole page bestie, mwah 🎀 — sourced from ./include/linux/atomic, dated October 2026, and she is literally the raw_atomic_l...dnot_release(9) manual. periodt. 💖🔥🦋
