xprt_register_transport(9)

🎀 NAME 🎀

xprt_register_transport — register a transport implementation. This is xprt_register_transport(9) from the Kernel API Manual, and it's basically the “hey RPC client, I exist” moment for a transport. 💅✨

✨ SYNOPSIS ✨

int xprt_register_transport (struct xprt_class *transport );

💅 ARGUMENTS 💅

• transport — transport to register. That's the one, bestie. 🫶

🦋 DESCRIPTION 🦋

Okay so here's the vibe: if a transport implementation is loaded as a kernel module, it can call this interface to make itself known to the RPC client. That's literally the whole plot. No cap. 💖

🌈 RETURN 🌈

• 0 — transport successfully registered.
• -EEXIST — transport already registered.
• -EINVAL — transport module being unloaded.
