mpt3sas_remo...ead_ioc_func(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay bestie, welcome to the Kernel API Manual — this page is mpt3sas_remove_dead_ioc_func(9), and yes the header up top is literally chopped to mpt3sas_remo...ead_ioc_func(9) because someone ran out of room 💀 but the full glow-up name is mpt3sas_remove_dead_ioc_func.

mpt3sas_remove_dead_ioc_func — kthread context to remove dead ioc. that's it, that's the vibe: it runs in kthread context to clean up a dead ioc. not "ioc" like your emotional state, like an ioc in the driver. 🫶

✨ SYNOPSIS ✨

int mpt3sas_remove_dead_ioc_func (void *arg );

literally the whole flex, look at it, int in, void *arg in the parens, and yes that space before the closing paren is staying, i don't make the rules 🎀

🎀 ARGUMENTS 🎀

  • arg — input argument, used to derive ioc. so bestie passes you arg, and you derive the ioc from it. that's the whole job. derive the ioc. no cap. 🦋

🌸 RETURN 🌸

  • 0 if controller is removed from pci subsystem.
  • -1 for other case.

so like, 0 = slay, the controller is gone from the pci subsystem, mission accomplished ✅. -1 = the other case, the "we don't talk about it" case 😭. it's giving "binary outcome, no in-between", periodt.

💖 SEE ALSO 💖

first up, the kernel file where all this lives, literally right here in the source tree:

  • ./drivers/scsi/mpt3sas/mpt3sas_base.c

and now the rest of the friend group, because apparently this driver has a lot of besties and every single one of them gets an invite to the group chat 🦋:

like i said. every single one. iykyk 💀👑

real talk bestie: that SEE ALSO list is not a suggestion, those are all legit (9) kernel API pages, so if you're debugging mpt3sas you've got the whole roster now 🫶

and that's the page!! sourced from ./drivers/scsi/mpt3sas, dated October 2026 — so future-girl math but the facts are timeless. bye bestie, go remove some dead iocs responsibly 💜✨🎀
