💅 time_is_before_eq_jiffies(9) 💅

okay so this is a page straight out of the Kernel API Manual, and bestie, it's a tiny little guy but it matters. Like, this is the kind of one-liner that keeps the whole kernel from being messy. main character energy in a single macro, fr fr ✨

🌸 NAME 🌸

time_is_before_eq_jiffies — returns true if a is before or equal to jiffies 💖

✨ SYNOPSIS ✨

time_is_before_eq_jiffies (a );

🎀 ARGUMENTS 🎀

• a — the time (an unsigned long, no cap) that you're comparing against jiffies 🫶

🦋 RETURN 🦋

it gives you true if the time a is before, or literally the exact same as, jiffies — otherwise you get false. that's it, that's the whole vibe check 💅

bestie please remember these comparisons only make sense when your time values are within a half-period of each other — that's the classic jiffies wraparound situation, so don't come for me if you compare wildly-far-apart times and get weird results 🙈
