rpcrdma_buffer_get(9)

💅 rpcrdma_buffer_get(9) — from the Kernel API Manual, bestie ✨

okay so picture this: it's a 9-section kernel API manual page, it lives in ./net/sunrpc/xprtrdma/verbs.c, and it's about getting yourself a request buffer. tiny page, huge main character energy. let's get into it 🎀

🌸 NAME 🌸

rpcrdma_buffer_get — Get a request buffer 🫶

✨ SYNOPSIS ✨

struct rpcrdma_req * rpcrdma_buffer_get (struct rpcrdma_buffer *buffers
);

like, yes, that's the whole signature, she's not complicated and honestly? iconic for that 💅

🦋 ARGUMENTS 🦋

• buffers — the buffer pool you're pulling a buffer out of. this is the source, the vibe supplier, the place the buffers live 💖

🔥 DESCRIPTION 🔥

Returns a fresh rpcrdma_req, or NULL if none are available.

and that's literally it — no cap. you call it, you either get a nice new request back or you get NULL and you have to Deal With That. the way this function is short and knows exactly what it is?? obsessed 😭✨

ngl bestie, NULL is a real answer here, not an error message. handle it. don't be weird about it 💀
