mpi3mr_memse...eq_q_buffers(9)

💅 NAME 💅

mpi3mr_memset_op_req_q_buffers — bestie, this one memsets the operational request queue's segments ✨ (yes, literally just zeroing out those queue segments, no cap)

So real talk, this little function lives in the kernel API manual for mpi3mr_memse...eq_q_buffers(9) (the title gets truncated like that, iykyk) and it's genuinely just here to wipe the op request queue's segments clean. Iconic lowkey behavior 🧚

---

🦋 SYNOPSIS 🦋

void mpi3mr_memset_op_req_q_buffers (struct mpi3mr_ioc *mrioc , u16 qidx );

It returns void, so like… it gives you nothing back and that's the whole point 💀

---

🌸 ARGUMENTS 🌸

• mrioc — your adapter instance reference, aka the whole controller vibe check 🫶
• qidx — the operational request queue index, so it knows which queue we're talking about 👑

---

⭐ RETURN ⭐

Nothing. Zero. Nada. She's a void function and she's at peace with that 🙈 (don't @ me looking for a return value, there isn't one)

---

🌈 SEE ALSO 🌈

Okay so this function has a whole friend group in the kernel file ./drivers/scsi/mpi3mr/mpi3mr_fw.c — like genuinely the entire mpi3mr cast, and we're listing every single one because we don't do half measures here 💖

Okay that's the whole page, bestie!! 💜 This gem came out of the ./drivers/scsi/mpi3mr directory, dated October 2026, and it's filed under the manual name mpi3mr_memse...eq_q_buffers(9). Go forth and memset responsibly, mwah 😭🎀
