__ibmvfc_work_to_do(9)

💅 __ibmvfc_work_to_do — like, is there task-level work to do or not??

okay bestie, welcome to the Kernel API Manual section for __ibmvfc_work_to_do, and honestly? the name says it all. it's the vibe check for the ibmvfc driver — it just looks around and is like "is there task level work to do?" 🔍✨

and the no locking part? that's not decorative, that's the whole personality. it means this bad boy does not grab any locks while it's snooping around, so you better already be holding whatever you need to be holding. iykyk 🔥

✨ SYNOPSIS ✨

int __ibmvfc_work_to_do (struct ibmvfc_host *vhost );

that's it. that's the whole signature. cute, right? 🎀

---

🌸 ARGUMENTS 🌸

• vhost — the ibmvfc host struct. literally the driver's host struct, that's what we're checking. nothing more, nothing less, no cap 💖

---

👑 RETURN 👑

• 1 — yes bestie, there's work to do 🔥
• 0 — nope, we're chilling, nothing to do 😴

that's the whole return contract. 1 if work to do, 0 if not. periodt 💅

ok but for real — notice how ibmvfc_dev_init_to_do(9) and ibmvfc_dev_logo_to_do(9) are in there too, plus the locked cousin ibmvfc_work_to_do(9)? this whole family is obsessed with asking "is there work to do". iconic behavior honestly 💀
