💅 mpi3mr_op_request_post(9) — Kernel API Manual, bestie edition

okay so you found the mpi3mr_op_request_post(9) page, iconic. this is a Linux kernel API man page (section 9, the "kernel internals" section, we love her) and it's all about yeeting an MPI3 request into the operational request queue. let's get into it 🎀

✨ NAME ✨

mpi3mr_op_request_post — post request to operational queue. that's it, that's the whole vibe. 🦋

✨ SYNOPSIS ✨

int mpi3mr_op_request_post (struct mpi3mr_ioc *mrioc , struct op_req_qinfo *op_req_q , u8 *req );

literally returns an int, takes three things, we move. 💅

✨ ARGUMENTS ✨

  • mrioc — the adapter reference 🫶 your controller, your main character
  • op_req_q — operational request queue info. yes queen, the queue deets
  • req — the MPI3 request itself ⭐

✨ DESCRIPTION ✨

so what does she do? she posts the MPI3 request into the operational request queue, then she tells the controller about it. informing the controller is like the whole point, no cap 📣

and if the queue is full? she returns the appropriate error. not gonna pretend it worked, she's honest like that 😭

✨ RETURN ✨

  • 0 on success 💖 (slay)
  • non-zero on failure 💀 (not slay, but at least you know)

✨ SEE ALSO ✨

okay bestie this list is LONG and every single one is here because we do not skip 😤 all from the kernel file ./drivers/scsi/mpi3mr/mpi3mr_fw.c:

ngl that's a lot of cross-references and they're all kept exactly as-is, typos and all, because that's the whole point of a man page bestie 💜

and that's the page! 🧚 from the kernel source path ./drivers/scsi/mpi3mr, dated October 2026 — go forth and post those requests responsibly, mwah 💋🌸
