iowait_starve_clear(9)

💖 NAME 💖

okay so bestie, this is iowait_starve_clear(9) from the Kernel API Manual, and its whole thing is literally clear the wait queue's starve count. That's the assignment. 💅✨

🌸 SYNOPSIS 🌸

void iowait_starve_clear (bool pkts_sent , struct iowait *w );

🦋 ARGUMENTS 🦋

• pkts_sent — have some packets been sent? 👀 That's the question this arg is answering.
• w — the iowait struct 🫶

🎀 DESCRIPTION 🎀

This function is called to clear the starve count. Cute. Simple. Iconic.

But no cap: if no packets have been sent, the starve count will not be cleared. So yeah, pkts_sent is lowkey running the whole vibe check here. Periodt. 😭💀
