ibmvfc_reenable_crq_queue(9)

💅 ibmvfc_reenable_crq_queue — from the Kernel API Manual, bestie ✨

okay so picture this: we're deep in the kernel docs, right, and the star of the show today is ibmvfc_reenable_crq_queue(9). yes the whole manual page. it's from the Kernel API Manual, and honestly it's giving "one tiny function with main character energy" 🌸

---

🎀 NAME 🎀

ibmvfc_reenable_crq_queue — the girlies are back, and she reenables the CRQ. that's it. that's the whole thing. slay 💅

---

🦋 SYNOPSIS 🦋

int ibmvfc_reenable_crq_queue (struct ibmvfc_host *vhost );

like, exactly that. no cap. 🫶

---

🌸 ARGUMENTS 🌸

• vhost — the ibmvfc host struct, aka the little data bundle you hand over so she knows which host we're talking about 💖

---

✨ DESCRIPTION ✨

so what does she do? she reenables the CRQ, periodt. and because every icon reports back, here's the vibe check on her return value:

• 0 — success, we ate, everyone's happy 🌈
• anything else — failure, and it's giving 😭💀

fr fr, that's the whole documented contract: 0 on success / other on failure. no extra lore, don't go inventing any 🙈
