mpi3mr_issue_diag_buf_post(9)

💖 mpi3mr_issue_diag_buf_post(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for mpi3mr_issue_diag_buf_post — yes the name is a mouthful, no I will not be shortening it, we respect the full government name here 🫶

---

✨ NAME ✨

mpi3mr_issue_diag_buf_post — literally just sends the diag buffer post req. that's the whole job. she's a one-task queen 👑

---

🌸 SYNOPSIS 🌸

int mpi3mr_issue_diag_buf_post (struct mpi3mr_ioc *mrioc , struct
diag_buffer_desc *diag_buffer );

---

🎀 ARGUMENTS 🎀

• mrioc — your adapter instance reference. the main character of the whole driver, honestly 💅
• diag_buffer — the diagnostic buffer descriptor. yes she's a struct, yes she's coming with us 🦋

---

⭐ DESCRIPTION ⭐

so here's the vibe: this function issues the diagnostic buffer post MPI request through the admin queue, and then it just waits — politely, patiently — for that request to complete. or for it to time out. whichever hits first 😭

no cap, that's it. send the request, wait for the completion, respect the timeout. iconic behaviour.

---

🔥 RETURN 🔥

• 0 on success — slay 💖
• non-zero on failures — not slay, but at least you know 🙈

🧚 quick vibe check: this page lives in ./drivers/scsi/mpi3mr and it's dated October 2026 — so yeah, this manual is from the future, we love a forward-thinking queen ⭐

okay that's the whole page, ily, go read your kernel source bestie 💜👑
