blk_set_pm_only(9)

💅 blk_set_pm_only

okay so bestie, welcome to the blk_set_pm_only(9) page — a Kernel API Manual moment, brought to you from the ./block corner of the kernel ✨

---

🌸 NAME 🌸

blk_set_pm_only — increment pm_only counter 🎀

Like, that's the whole job. It increments the pm_only counter. Iconic, lowkey minimalist, we love a function with a clear purpose 💖

---

✨ SYNOPSIS ✨

void blk_set_pm_only (struct request_queue *q );

That's it, that's the whole signature. Returns void, so don't be out here expecting a return value, bestie — it's giving "I do my thing and I leave" 💅

---

🦋 ARGUMENTS 🦋

• q — request queue pointer 🌈 (literally a pointer to a struct request_queue, that's the vibe)

---
