mpi3mr_release_diag_bufs(9)

💅 mpi3mr_release_diag_bufs(9) — like, the Kernel API Manual page you didn't know you needed

okay so bestie. welcome to the Kernel API Manual entry for mpi3mr_release_diag_bufs, and yes it's a whole vibe. sit down, grab a matcha, we're doing kernel cleanup today 🧹✨

---

🌸 NAME 🌸

mpi3mr_release_diag_bufs — Release diag buffers. that's it, that's the tweet. literally just releasing the diag buffers 🎀

---

✨ SYNOPSIS ✨

void mpi3mr_release_diag_bufs (struct mpi3mr_ioc *mrioc , u8
skip_rel_action );

not me writing this out exactly as it lives, spacing and all, because that's the whole point 🙈

---

🦋 ARGUMENTS 🦋

• mrioc — the adapter instance reference 💜 like, the pointer to the controller we're out here doing stuff to
• skip_rel_action — Skip release action and set buffer state. yes bestie that's the actual description, it does what it says on the tin: skip the release action and just set the buffer state instead ⭐

---

👑 DESCRIPTION 👑

okay so here's the tea 🍵: this function calls a helper function to release both the trace buffers and the firmware buffers from the controller. both. at once. iconic behavior honestly 💅🔥

one function, helper does the heavy lifting, buffers get released, everyone goes home. main character energy fr fr 🫶

---

🌈 RETURN 🌈

None. zero. nada. it's giving void and she's at peace with that 💖

okay bye bestie!! this one came from the source path ./drivers/scsi/mpi3mr, dated October 2026, and it's living happily in the Kernel API Manual 🎀🦋 slay, periodt, see you at the next man page ✨💅
