rpc_run_bc_task(9)

💅 rpc_run_bc_task(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the Kernel API Manual, and buckle up because this one is short but it's mighty ✨. We're talking about rpc_run_bc_task — yes, the "bc" is backchannel, and yes, it's giving main character energy in the SunRPC world 🦋.

---

🌸 NAME 🌸

rpc_run_bc_task — literally allocates a brand-new RPC task for backchannel use, then runs rpc_execute against it 💫. That's it. That's the whole vibe. No cap, it does exactly what it says on the tin.

---

✨ SYNOPSIS ✨

struct rpc_task * rpc_run_bc_task (struct rpc_rqst *req , struct rpc_timeout *timeout );

like... look at that signature. it's gorgeous. it returns a struct rpc_task *, bestie 🫶

---

👑 ARGUMENTS 👑

• req — the RPC request, periodt. This is the thing you're handing over so the task has something to do 💌
• timeout — the timeout values to use for this task, fr fr. This is where you tell it how long it's allowed to wait before things get awkward 😭

---

🔥 SEE ALSO 🔥

Kernel file ./net/sunrpc/clnt.c — that's where the magic lives, iykyk 👀

ngl bestie, if you only remember one thing: it makes the task, then it runs rpc_execute on it. that's the whole plot. slay 🧚
