the og kernel file lives at ./drivers/scsi/lpfc/lpfc_attr.c and it's surrounded by an absolutely massive friend group — here's literally every single one, no skips, i would never 🙈

and that's the whole page, bestie 🫶 this icon lives in ./drivers/scsi/lpfc, dropped in October 2026, and it answers to the name lpfc_oas_lun_state_change(9). go forth and set those lun states 💜✨
