xprt_switch_get(9)

okay bestie, welcome to the Kernel API Manual — today we're looking at xprt_switch_get(9), and it's giving tiny-but-important refcount behavior. ✨

🌸 NAME 🌸

xprt_switch_get — Return a reference to a rpc_xprt_switch. That's the whole assignment, and it ate. 💅

✨ SYNOPSIS ✨

struct rpc_xprt_switch * xprt_switch_get (struct rpc_xprt_switch *xps );

🎀 ARGUMENTS 🎀

• xps — pointer to struct rpc_xprt_switch. That's the thing you're passing in, bestie. 🫶

💖 DESCRIPTION 💖

Returns a reference to xps unless the refcount is already zero. So the refcount-zero case is the exception — that is not the moment you get a reference from this function, and that's the whole vibe. 🙈💀
