raw_atomic_l...read_acquire(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 raw_atomic_long_read_acquire — NAME 💅

okay bestie so raw_atomic_long_read_acquire is literally an atomic load with acquire ordering ✨ and she's from the Kernel API Manual (section 9, kernel devs only, iykyk 🎀). that's the whole name. no notes. periodt.

✨ SYNOPSIS ✨

long raw_atomic_long_read_acquire (const atomic_long_t *v );

like, she takes one pointer and hands you back a long. that's it. that's the whole girl 🫶

🦋 ARGUMENTS 🦋

  • v — pointer to atomic_long_t. yes that's the entire description. she's a pointer to an atomic_long_t. iconic, minimal, no cap 🔥

👑 DESCRIPTION 👑

so what she does is atomically load the value of v with acquire ordering 💖 like, one clean read, no torn values, and the acquire ordering means everything is ordered properly around it. slay.

she is safe to use in noinstr code — that's the whole reason she exists as a raw_ version, bestie 🌟

🫶 but like... prefer atomic_long_read_acquire elsewhere. raw_atomic_long_read_acquire is the noinstr-safe one; the regular atomic_long_read_acquire is the one you should be reaching for in normal code. the way that's literally in the manpage, so don't come for me 💀

💜 RETURN 💜

the value loaded from v. she read it, she gives it to you, done. no errors, no surprises, main character energy only 👑✨

🌈 SEE ALSO 🌈

okay this is the part where she introduces you to her entire extended family 😭 — like genuinely all of them, so buckle up 🍓. and the kernel file that houses this whole dynasty:

like... 84 cousins. she's got a big family and she loves them all 💜✨

bye bestie!! 💖 this page lives at ./include/linux/atomic, and it was stamped October 2026 — so go forth, load atomically, and stay noinstr-safe 🧚‍♀️🎀⭐
