💅 lpfc_aer_cleanup_state(9) — your girl's guide to the Linux Kernel API Manual 🎀

okay so bestie, welcome to lpfc_aer_cleanup_state(9), the kernel API manual entry that's genuinely doing the most for a function with a four-part signature. lowkey iconic of it. pull up a chair, we're learning 💖

✨ NAME ✨

lpfc_aer_cleanup_state — clean up aer state to the aer enabled device 🧹

🌸 SYNOPSIS 🌸

ssize_t lpfc_aer_cleanup_state (struct device *dev , struct device_attribute *attr , const char *buf , size_t count );

yes that's the whole thing, no cap. four arguments, one ssize_t return. she's thorough 💅

🦋 ARGUMENTS 🦋

  • dev — the class device that gets converted into a Scsi_host. glow-up machine fr fr.
  • attr — the device attribute. and… it's not used. she's just here for moral support 🫶
  • buf — the buffer that contains flag 1 for the aer cleanup state. 1 is the whole vibe.
  • count — unused variable. we love an unbothered icon who contributes nothing but good energy ✨

💜 DESCRIPTION 💜

so here's the tea: if buf contains 1, this function invokes the kernel AER helper routine pci_aer_clear_nonfatal_status to clean up the uncorrectable error status register. that's it. that's the function. she cleans, she clears, she leaves 🌈

not me being obsessed with a function that does exactly one thing and does it well. main character energy 👑

🎀 NOTES 🎀

nothing here bestie. the original left this section empty and honestly? respect. sometimes the absence of chaos is the vibe 🙈

⭐ RETURN ⭐

  • -EINVAL — returned if buf does not contain 1. wrong number, wrong energy, respectfully declined 💀
  • -EPERM — returned if the OS cannot clear AER error status, i.e., when platform firmware owns the AER Capability. your firmware has custody, bestie, and it's not sharing 😭

🦄 SEE ALSO 🦄

okay so THIS is the part where the manpage absolutely ate and left no crumbs. the kernel file lives at ./drivers/scsi/lpfc/lpfc_attr.c, and the whole friend group is listed below. every single one. i counted, don't worry 💅

bestie if you read all 111 of those you're literally a scholar. iykyk 🎓✨

and that's the page! 💖 this little love letter lives under ./drivers/scsi/lpfc, dated October 2026, and the whole thing is filed under the manual name lpfc_aer_cleanup_state(9) in case you ever need to find her again. mwah, go clear some error status, periodt 🦋💅
