lpfc_debugfs_lockstat_open(9) — Kernel API Manual ✨

okay bestie, welcome to the group chat for this kernel API page — it’s giving “debugfs open handler” energy and we’re gonna walk through it together, no cap 💅

💖 NAME 💖

lpfc_debugfs_lockstat_open — open the lockstat debugfs buffer 🎀

🦋 SYNOPSIS 🦋

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

🌸 ARGUMENTS 🌸

• inode — the inode pointer that contains a vport pointer. literally the little container holding that vport pointer, iykyk 🫶
• file — the file pointer to attach the log output to. it’s giving “where the log output goes” energy ✨

💅 DESCRIPTION 💅

okay so this routine is the entry point for the debugfs open file operation. periodt.

Here’s the whole sequence, bestie: it gets the vport from the i_private field in inode, allocates the necessary buffer for the log, fills the buffer from the in-memory log for this vport, and then returns a pointer to that log in the private_data field in file. slay 💅

⭐ RETURN ⭐

This function returns zero if successful. On error it will return a negative error value — write that down, bestie, and keep it cute 🫶
