ibmvscsi_reset_crq_queue(9)

💅 ibmvscsi_reset_crq_queue(9) — like, the Kernel API Manual era 🎀

okay so bestie, this is a page from the Kernel API Manual, and it's literally about ibmvscsi_reset_crq_queue — the function that hits the reset button on a CRQ when everything's gone sideways. no cap, it's a whole vibe.

---

✨ NAME ✨

ibmvscsi_reset_crq_queue — resets a crq after a failure 💀

like the emotional-support reboot of the CRQ world. something broke, and this is the function that picks it back up and goes "ok we're trying again."

---

🌸 SYNOPSIS 🌸

int ibmvscsi_reset_crq_queue (struct crq_queue *queue , struct
       ibmvscsi_host_data *hostdata );

she returns an int, she takes two structs, she's booked and busy 🫶

---

🦋 ARGUMENTS 🦋

• queue — the crq_queue we're gonna initialize and register. like, this is her moment, the queue gets set up and put on the list. main character energy fr.
• hostdata — the ibmvscsi_host_data of the host. literally just the host's whole info situation, handing it over so it knows whose queue we're resetting 💖
