xprt_reques...ceive_locked(9)

💅 xprt_reques...ceive_locked(9)

okay so first things first — this one comes out of the Kernel API Manual (section 9, bestie, we're in kernel-space now ✨). And yes, the header literally shows the name all squished up like xprt_reques...ceive_locked(9) because the full thing is way too long to fit. The real, un-cut name is xprt_request_dequeue_receive_locked and it is a whole mouthful, so honestly? Respect the ellipsis. 💀
