💅 ioc_reset_count_show(9) — the kernel manual, but make it make sense

Hey bestie, welcome to the ioc_reset_count_show(9) page from the Kernel API Manual. Yes that's a mouthful, no I will not be shortening it. This is the whole vibe: a little sysfs show function that tells you about the ioc reset count. Let's get into it 🫶

✨ NAME ✨

ioc_reset_count_show — literally the ioc reset count. That's it. That's the name section. Iconic behavior honestly 🎀

🌸 SYNOPSIS 🌸

ssize_t ioc_reset_count_show (struct device *cdev , struct
       device_attribute *attr , char *buf );

That's the signature, copied exactly, do not come for me about the spacing 💀

🦋 ARGUMENTS 🦋

  • cdev — pointer to embedded class device. Your device-y entry point, main character energy.
  • attr — ? … yeah. That's what the page says. A whole question mark. The docs simply did not know and honestly? Respect for the honesty 😭
  • buf — the buffer returned. This is where the output goes, it's giving delivery slot 📦

💖 DESCRIPTION 💖

So what does this thing actually do? This is firmware queue depth limit.

Lowkey that is the entire description. It's also a sysfs 'read-only' shost attribute — so read it, love it, admire it, but you're not writing to it, bestie. No cap 🔥

👑 SEE ALSO 👑

Bestie the cross-reference list here is long long. Buckle up, we're listing every single one, fr fr. First up, the kernel file they live in: ./drivers/scsi/mpt3sas/mpt3sas_ctl.c.

Like I said. Long long. But you have them all now, so go be curious 💜

That's the whole page bestie — no options list, no exit statuses, no environment variables, just the reset count and a truly enormous friend group ✨

And that's a wrap! 🎀 This one came from ./drivers/scsi/mpt3sas, dated October 2026 — go forth and read your sysfs attributes responsibly, mwah 💋
