💅 mpi3mr_devstatuschg_evt_bh(9) — DevStatusChange evt bottomhalf

okay so real quick bestie, this page lives in the Kernel API Manual, section 9 ofc, and it's about one tiny little function that has main character energy in the mpi3mr driver's event-handling storyline. sit down, hydrate, let's go 🍓

✨ NAME ✨

mpi3mr_devstatuschg_evt_bh — literally the bottomhalf for the DevStatusChange event 💫

🦋 SYNOPSIS 🦋

void mpi3mr_devstatuschg_evt_bh (struct mpi3mr_ioc *mrioc , struct mpi3mr_fwevt *fwevt );

she takes two args, she returns nothing, she's booked and busy ✨

🌸 ARGUMENTS 🌸

  • mrioc — the adapter instance reference, aka your card's little passport 🫶
  • fwevt — the firmware event information, aka the actual tea about what happened 🔥

👑 DESCRIPTION 👑

so here's the vibe: this function processes the Device status Change event. and then, based on the device's new information, it does one of exactly two things — no in-between, no "it's complicated":

  • expose the device to the upper layers (welcome to the group chat, bestie 🎀), or
  • remove the device from upper layers (okay bye, we're removing you from the chat 💀)

that's it, that's the whole plot. device changed status, we act accordingly. periodt.

⭐ RETURN ⭐

Nothing. genuinely nothing. it's a void function, no value comes back, no gifts, no "u up?" text. 😭

🌈 SEE ALSO 🌈

the kernel file she's chillin' in:

and now the full roster, the entire extended universe, every single one, no skips, iykyk 👑:

ngl that's a lot of cross-references but we read every single one, no cap 💅

and that's the page bestie!! one last cute sign-off: this whole thing comes from the source tree at ./drivers/scsi/mpi3mr, dated October 2026 🎀 go forth and handle those device status changes, you're gonna slay 💖✨
