🌸 ctl_iop1_count_show(9) 🌸

okay so bestie, welcome to the Kernel API Manual 💖 — yes we're in the kernel docs now, and honestly? iconic behavior. this little page is all about ctl_iop1_count_show, which is this tiny sysfs show function living over in the pm8001 SCSI controller world. iop1 count check, that's the whole vibe. let's get into it ✨

✨ NAME ✨

ctl_iop1_count_show — controller iop1 count check 🎀

like, it checks the count. for iop1. on the controller. slay 💅

🦋 SYNOPSIS 🦋

ssize_t ctl_iop1_count_show (struct device *cdev , struct
device_attribute *attr , char *buf );

it returns a ssize_t, bestie. that's the number (or the sad negative error, we don't talk about those) 📏

💜 ARGUMENTS 💜

  • cdev — pointer to embedded class device 🫶 this is the device we're doing the whole thing on, main character energy
  • attr — device attribute, and ngl it's unused here 😭 just vibing in the parameter list. we don't touch it. it's there for the formula
  • buf — the buffer returned 📝 this is where the goods go

🌈 DESCRIPTION 🌈

A sysfs 'read-only' shost attribute 👑

so it's read-only, right? you can look but you cannot touch. no writing to this one, no cap. it's a shost attribute in sysfs and that's the entire description the kernel gods gave us, and honestly? respect for the brevity 🔥

🧚 SEE ALSO 🧚

the kernel file it lives in, bestie:

  • ./drivers/scsi/pm8001/pm8001_ctl.c 📁

and the whole friend group of show functions it runs with — like a group chat where everyone has _show in their name 💀:

(iop0's sibling said hi 👋 — and yeah ctl_iop1_count_show itself is right there in the list too, we contain multitudes 💫)

okay so real talk: this page gives us the function, the args, and one line of description. that's it. that's the whole tea 🍵 don't @ me, @ the kernel maintainers — they're the ones who wrote it this short 🙈

and that's the page, bestie!! 🎀 this one came straight out of ./drivers/scsi/pm8001 and it's dated October 2026 ⭐ so go forth and read your sysfs attributes responsibly 💖 mwah 💋
