💅 time_before_eq64(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes we're literally in kernel land today, get comfy 🎀

✨ NAME ✨

time_before_eq64 — returns true if the time a is before or the same as time b. that's it. that's the whole vibe check 💖

🌸 SYNOPSIS 🌸

time_before_eq64 (a , b );

look at her. two args, zero drama, doing exactly what she says on the tin ✨

🦋 ARGUMENTS 🦋

  • a — first comparable, typed as __u64 💅
  • b — second comparable, also typed as __u64 🫶

both of them are __u64, no cap. don't be out here passing her anything else 😭

🔥 DESCRIPTION 🔥

okay so this is the one you must use when you're working with jiffies_64 — like, specifically "i.e. return value of get_jiffies_64". that's the whole rule. this function is literally built for the 64-bit jiffies girlies 💀

so if you're holding a jiffies_64 value and you're like "hmm is this before or equal to that other one", she's your girl 👑

👑 RETURN 👑

true if time a is before or the same as time b, otherwise false. so straightforward. we love a binary queen 🌈

ngl, if you were hoping for a third option — there isn't one. it's true or false, periodt 💅
