rdma_restrack_add(9)

💖 rdma_restrack_add — the kernel API manual, but make it make sense

okay bestie so this is rdma_restrack_add(9) from the Kernel API Manual and honestly? it's kind of a baddie with a warning label. let's get into it 🎀

✨ NAME ✨

rdma_restrack_add — add an object to the resource tracking database 🗂️

like, you're literally putting your resource in the group chat so everybody knows it exists. but here's the plot twist, and it's giving cautionary tale: if this resource reuses an ID of a resource that was already destroyed — specifically, one that got destroyed after calling rdma_restrack_begin() but didn't yet call rdma_restrack_commit_del() — it can result in an untracked QP. 😭 and an untracked QP is exactly the kind of thing that does NOT pass the vibe check. no cap.

---

🌸 SYNOPSIS 🌸

void rdma_restrack_add (struct rdma_restrack_entry *res );

that's it. one function, void return, no drama in the signature. slay.

---

🦋 ARGUMENTS 🦋

• res — the resource entry 💜 she's the star of the show. that's the struct rdma_restrack_entry * you're handing over so she can get properly tracked, main character energy and all.
