version_mpi_show(9)

🌸 version_mpi_show(9) — the Kernel API Manual, bestie edition 🌸

okay so you're reading a page from the Kernel API Manual, section 9, and today's main character is version_mpi_show — literally the MPI (message passing interface) version, no cap 💅

---

✨ NAME ✨

version_mpi_show — MPI (message passing interface) version 🦋

---

🎀 SYNOPSIS 🎀

ssize_t version_mpi_show (struct device *cdev , struct device_attribute
*attr , char *buf );

---

💖 ARGUMENTS 💖

• cdev — pointer to embedded class device ✨
• attr — ? ... yeah bestie, that's literally what the page says. We don't know. It's giving mystery, it's giving "the docs said 🤷". I'm not gonna invent a meaning for it, periodt.
• buf — the buffer returned 🧺

---

👑 DESCRIPTION 👑

A sysfs 'read-only' shost attribute. That's the whole vibe check — read-only, so admire it with your eyes, don't try to write to it 💀

lowkey iconic that one little _show function rolls with this many friends 🫶

and that's the page, bestie! 🌈 this one came from ./drivers/scsi/mpt3sas, dropped October 2026, and it's living in the Kernel API Manual (section 9) — mwah, go read some more man pages, ily 😭💖
