__timekeepin...ct_sleeptime(9)

🌸 NAME 🌸

okay so welcome to the Kernel API Manual, bestie 💖 — this page is all about __timekeeping_inject_sleeptime, aka the internal function to add sleep interval. she’s not the public-facing main character, she’s the internal bestie doing the suspend-time math. periodt.

✨ SYNOPSIS ✨

void __timekeeping_inject_sleeptime (struct timekeeper *tk , const
       struct timespec64 *delta );

🎀 ARGUMENTS 🎀

• tk — pointer to the timekeeper that’s getting updated. like, this is the clock bestie receiving the glow-up 💅
• delta — pointer to the delta value, in timespec64 format. this is the offset cutie that gets added in.

🦋 DESCRIPTION 🦋

so basically this function takes a timespec offset that measures a suspend interval, and properly adds the sleep offset to the timekeeping variables. no cap, that’s the whole vibe: suspend sleep time goes in, timekeeping variables get the correct offset. ⭐
