mpi3mr_clear_scmd_priv(9)

💅 mpi3mr_clear_scmd_priv(9) — from the Kernel API Manual, section 9, bestie

okay so hi 🫶 you're looking at a page from the Kernel API Manual, section 9 (that's the kernel-API section, iykyk). The function's name is mpi3mr_clear_scmd_priv, and like… it's a tiny little cleanup gremlin and I'm obsessed with how simple it is. Let's get into it ✨

---

🎀 NAME 🎀

mpi3mr_clear_scmd_priv — Cleanup SCSI command private date

and yes bestie, the page really does say “date” and not “data” 💀 I'm not fixing it, I'm just delivering it to you exactly as it was written. Iconic typo behavior, no cap.

---

✨ SYNOPSIS ✨

void mpi3mr_clear_scmd_priv (struct mpi3mr_ioc *mrioc , struct scsi_cmnd
*scmd );

so it returns void (nothing comes back out, it's giving "I do my job and I leave 🌸") and it takes exactly two things. That's the whole vibe check.

---

🦋 ARGUMENTS 🦋

• mrioc — the adapter instance reference 💜 like, the whole controller/driver instance this command belongs to.
• scmd — the SCSI command reference, aka the actual command we're tidying up after.

two args, zero drama, we love to see it 🎀

---

🌸 DESCRIPTION 🌸

here's the tea ☕: mpi3mr_clear_scmd_priv invalidates the SCSI command private data, and the whole point of doing that is to mark the command as not in LLD scope anymore — LLD being the low-level driver, bestie, so basically "this command is no longer ours, hands off 👋".

it doesn't return anything useful, it doesn't do a little dance, it just marks the thing as out of scope. tiny function, big main character energy 👑✨

---

🌈 RETURN 🌈

Nothing. 🫶 like, literally nothing comes back. void. it's giving "I gave you closure, not a value" 💅

okay that's the page, bestie 💖 it comes to you courtesy of the kernel source directory ./drivers/scsi/mpi3mr, dated October 2026, and the page itself is mpi3mr_clear_scmd_priv(9). go forth and clear those private data (dates? 💀) and slay ✨👑🎀
