time_after_eq(9)

💖 time_after_eq(9) — kernel API manual, bestie edition 💖

okay so welcome to the Kernel API Manual, section 9, and today's main character is time_after_eq — a tiny little bool-returning baddie from the kernel. she's not complicated, she's not doing too much, she's just here to answer one (1) question for you. and honestly? she ate. 🎀

✨ NAME ✨

time_after_eq — returns true if the time a is after or the same as time b.

like literally that's it, that's the whole job. no cap. 🫶

🦋 SYNOPSIS 🦋

bool time_after_eq (u64 a , u64 b );

that's the whole signature, bestie — copy it exactly, commas and spacing and all, because the kernel does not play about formatting. 💅

🌸 ARGUMENTS 🌸

  • a — first comparable as u64. she's the first one up for comparison, okay? give her her moment. ✨
  • b — second comparable as u64. the other half of this whole comparison situation. 🦋
both of these are u64, fr fr. don't be sneaky and slide a different type in there, that's not the vibe. 🙈

🔥 RETURN 🔥

true is time a is after or the same as time b, otherwise false.

(yes, the original says "true is time *a*…" — that's the manpage's wording, not a typo on my end, i'm just the messenger 💀)

so like, a strictly after b? true. a exactly equal to b? also true, because the _eq is right there in the name, bestie, it's giving inclusive. 👑 anything else? false. periodt.

💜 SEE ALSO 💜

Kernel file ./tools/sched_ext/include/scx/common.bpf.h — that's where she lives, go say hi. 🏠

and then the whole friend group, in exactly this order:

the time family is lowkey a whole squad and time_after_eq is absolutely part of the core friend group. iykyk. 🌈

ok that's the whole page! no options, no environment variables, no exit statuses, no signals, no bugs section — just a very good little comparison function living her best life in the kernel. don't go inventing flags for her, she doesn't have any. 😭

and that's a wrap, bestie!! 💖✨🎀 this iconic little page came to you from ./tools/sched_ext/include/scx, dated October 2026, and it's filed under time_after_eq(9) in the Kernel API Manual — section 9, where all the cool kernel-internal kids hang out. mwah. 💅🫶🍓
