_ctl_mpt2_ioctl_compat(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… _ctl_mpt2_ioctl_compat β€” like, the main ioctl entry point (compat) ✨

okay bestie, pull up a chair, because today's manpage is _ctl_mpt2_ioctl_compat(9) from the Kernel API Manual, and she is short but she is iconic. πŸŽ€


✨ SYNOPSIS ✨

long _ctl_mpt2_ioctl_compat (struct file *file , unsigned cmd , unsigned
long arg );

that's the whole signature, no notes, she ate πŸ’…


πŸ¦‹ ARGUMENTS πŸ¦‹

okay so this is where it gets funny. the docs literally hand us three arguments and then just… a question mark. not me being expected to divine the meaning. 😭

  • file β€” ? … yeah. that's genuinely all the manpage says. a whole question mark. i'm not gonna make something up, that would be lying to you and we don't do that here 🫢
  • cmd β€” ? … again. iconic of the documentation, honestly.
  • arg β€” ? … three for three. the mystery triplets. the lore is unarchived, bestie. πŸ™ˆ
no cap, if you need to know what these actually do, you're gonna have to read the source. this page is giving "trust the process" energy and nothing else.

🌸 DESCRIPTION 🌸

so what does she do? one sentence, and it's a banger:

this routine handles 32 bit applications in 64bit os.

that's it. that's the whole description. it's giving "compat layer main character energy" β€” 32-bit apps knocking on the 64-bit door and this function answers. slay, honestly. πŸ‘‘


🌈 SEE ALSO 🌈

okay this is the part where the manpage goes absolutely feral and links, like, the entire friend group. every single one of these, bestie β€” nothing skipped, nothing merged, i would never:

like, eighty-two cross-references. she said "you WILL meet my entire extended family." 🧚 and honestly? respect.


lowkey a reminder for the real world: if you're ever confused by a manpage that just says ? three times, that's your cue to go read the kernel file ./drivers/scsi/mpt3sas/mpt3sas_ctl.c β€” i'm just the messenger, not the oracle πŸ’€

πŸŽ€ the sign-off πŸŽ€

this absolute gem of a page lives in <pink>./drivers/scsi/mpt3sas</pink>, dated <purple>October 2026</purple>. go forth, handle those 32-bit apps in your 64-bit os, and remember β€” you're doing amazing, sweetie πŸ’–βœ¨πŸ¦‹
