lpfc_fwrev_show(9)

💖 NAME 💖

okay so bestie, this is lpfc_fwrev_show(9), straight out of the Kernel API Manual, and its whole deal is: lpfc_fwrev_show — Return the firmware rev running in the hba. no cap, that's the mission. ✨

📜 SYNOPSIS 📜

ssize_t lpfc_fwrev_show (struct device *dev , struct device_attribute
       *attr , char *buf );

🧚 ARGUMENTS 🧚

quick vibe check on the args, bestie:

• dev — class converted to a Scsi_host structure. yes, that's the pipeline.
• attr — device attribute, not used. it's literally just there for the function-signature aesthetic 💅
• buf — on return contains the scsi vpd program type. that's the payload, periodt.

🔥 RETURN 🔥

size of formatted string. that's the whole return vibe — the size, periodt. 💖
