lpfc_debugfs_hbqinfo_open(9)

Okay so bestie, this is the Kernel API Manual page for lpfc_debugfs_hbqinfo_open, and it is literally here to open the hbqinfo debugfs buffer. Main character energy only 💅✨

---

💖 NAME 💖

lpfc_debugfs_hbqinfo_open — open the hbqinfo debugfs buffer 🎀

---

✨ SYNOPSIS ✨

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

---

🎀 ARGUMENTS 🎀

• inode — the inode pointer that contains a vport pointer. Yes, the vport is lowkey nested in there 🫶
• file — the file pointer to attach the log output to.

---

🦋 DESCRIPTION 🦋

Bestie, this routine is the entry point for the debugfs open file operation. The way it works is: 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. That’s the whole flow — iconic, honestly 🦋💖

---

🔥 RETURN 🔥

This function returns zero if successful. On error it will return a negative error value. So yeah, 0 is the slay outcome, negative is the “oop” outcome 😭💀
