✨ iowait_queue(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one's called iowait_queue, and it's literally the "put the iowait on a wait queue" girlie. that's the whole vibe. 💅

🌸 NAME 🌸

iowait_queue — Put the iowait on a wait queue 🎀

🦋 SYNOPSIS 🦋

void iowait_queue (bool pkts_sent , struct iowait *w , struct list_head
*wait_head );

💖 ARGUMENTS 💖

  • pkts_sent — a bool, bestie: have some packets been sent before queuing? that's the question it answers 👀
  • w — the iowait struct itself. the main character, honestly ✨
  • wait_head — the wait queue. the guest list. the venue. 🎀

🧚 DESCRIPTION 🧚

so this function gets called to insert an iowait struct into a wait queue — and it happens after a resource has run out (like, for example, an sdma descriptor or a pio buffer). think of it as: the resource said "i'm full, no more for you 💀" and now your iowait goes and waits its turn on the queue. no cap, that's it. 🫶
