get_allowed_ops(9)

🌸 get_allowed_ops — Kernel API Manual 🌸

okay so bestie, welcome to the little corner of the kernel manual that explains get_allowed_ops, and honestly? it's giving "small function, big responsibility" energy. it's from the Kernel API Manual, section 9 (that's the kernel devs' club, iykyk 💅).

---

✨ NAME ✨

get_allowed_ops — given a QP type, return the appropriate allowed OP. that's it, that's the whole gig. short queen behavior 👑

---

🦋 SYNOPSIS 🦋

u8 get_allowed_ops (enum ib_qp_type type );

literally one function, one argument, returns a u8. no cap, that's the whole signature.

---

🎀 ARGUMENTS 🎀

• type — a valid, supported, QP type. that's the vibe check: it has to be valid and supported, so don't come at this function with just any old garbage value and expect it to slay. it's enum ib_qp_type, periodt.

💖 reminder bestie: type needs to be a valid, supported QP type. the manual says so, and the manual is never gonna set you up like that.
