🌸 SYNOPSIS 🌸

void xprt_rdma_alloc_slot (struct rpc_xprt *xprt , struct rpc_task *task

🦋 ARGUMENTS 🦋

• xprt — the controlling RPC transport, aka the main character handling the transport vibes ✨

💖 DESCRIPTION 💖

so here’s the tk_status situation, no cap:

• 0 if task->tk_rqstp points to a fresh rpc_rqst 👑

that’s literally the whole status check vibe, fr fr 🫶
