rpcrdma_mr_get(9)

💅 rpcrdma_mr_get(9) ✨

okay so this is a page from the Kernel API Manual and it's all about rpcrdma_mr_get, which lowkey does exactly what the name says: it gets you an rpcrdma_mr 🎀 read on bestie, it's short but it eats.

---

🌸 NAME 🌸

rpcrdma_mr_get — Allocate an rpcrdma_mr object 💖

---

✨ SYNOPSIS ✨

struct rpcrdma_mr * rpcrdma_mr_get (struct rpcrdma_xprt *r_xprt );

---

🦋 ARGUMENTS 🦋

• r_xprt — the controlling transport, like the main character of this whole operation 👑 it's the one in charge, periodt.

---

💜 DESCRIPTION 💜

So what does it actually do? It returns an initialized rpcrdma_mr ✨ or NULL if no free rpcrdma_mr objects are available 😭 that's it, that's the whole vibe. Either you get your object, or you get NULL and have to deal with it, ngl.

fr fr check for that NULL bestie, it's giving "no free objects rn" 💀
