lpfc_debugf...ripools_open(9)

🎀 NAME 🎀

okay so welcome to the lpfc_debugf...ripools_open(9) page from the Kernel API Manual 💅 this is the entry for lpfc_debugfs_multixripools_open, aka the multixripool debugfs buffer opener, and she is lowkey iconic.

✨ SYNOPSIS ✨

int lpfc_debugfs_multixripools_open (struct inode *inode , struct file
*file );

🌸 ARGUMENTS 🌸

• inode — the inode pointer that contains a hba pointer. She's the one holding the hba hookup, iykyk.
• file — the file pointer to attach the log output. This is where the log output gets attached, periodt.

💖 DESCRIPTION 💖

This routine is the entry point for the debugfs open file operation.

It gets the hba from the i_private field in inode, allocates the necessary buffer for the log, fills the buffer from the in-memory log for this hba, and then returns a pointer to that log in the private_data field in file. No cap, that's the whole flow ✨

🫶 RETURN 🫶

This function returns zero if successful. On error it will return a negative error value. So zero is the slay outcome; negative means something went sideways, bestie 😭
