💖 timespec64_add_ns(9) 💖

okay bestie, this is a page straight out of the Kernel API Manual, and we're talking about timespec64_add_ns. It’s giving tiny helper, big vdso energy, and honestly? iconic. 🫶

🌸 NAME 🌸

timespec64_add_ns — literally adds nanoseconds to a timespec64. no cap. ✨

🎀 SYNOPSIS 🎀

void timespec64_add_ns (struct timespec64 *a , u64 ns );

💅 ARGUMENTS 💅

• a — pointer to the timespec64 that’s getting incremented. like, you’re handing over the address so it can get bumped. 🎀
• ns — the unsigned nanoseconds value to be added. it’s a u64, periodt. 💜

🔥 DESCRIPTION 🔥

This one must always be inlined — and bestie, that is not a vibe suggestion, it’s a requirement. Why? because it’s used from the x86-64 vdso, which cannot call other kernel functions. so it has to be all up in the caller’s business. 🧚✨
