rpcrdma_xprt_disconnect(9)

✨ NAME ✨

okay bestie, welcome to the rpcrdma_xprt_disconnect(9) page from the Kernel API Manual — this one is literally about disconnecting the underlying transport 💅

rpcrdma_xprt_disconnect — disconnect the underlying transport. no cap.

🌸 SYNOPSIS 🌸

void rpcrdma_xprt_disconnect (struct rpcrdma_xprt *r_xprt );

she takes one arg and returns void, periodt ✨

🎀 ARGUMENTS 🎀

• r_xprt — controlling transport instance. that's the main character struct here 👑

🦋 DESCRIPTION 🦋

okay so the caller serializes — literally. Either the transport send lock is held, or we're being called to destroy the transport. both vibes are valid 🫶

On return, r_xprt is completely divested of all hardware resources and prepared for the next ->connect operation. she's clean, she's ready, she's giving fresh-start energy ✨
