💅 lpfc_debugfs_hdwqstat_data — Kernel API Manual ✨

okay so bestie, buckle in, because today we're looking at lpfc_debugfs_hdwqstat_data from the Kernel API Manual, and she is literally the main character of your debugfs stat dumping era 🎀

---

✨ NAME ✨

lpfc_debugfs_hdwqstat_data — Dump I/O stats to a buffer 🦋

---

🌸 SYNOPSIS 🌸

int lpfc_debugfs_hdwqstat_data (struct lpfc_vport *vport , char *buf ,
       int size );

---

💖 ARGUMENTS 💖

• vport — the vport you're pulling target node info out of 👑 like, this is the one we're snooping on, no cap
• buf — the buffer we're dumping the log into 🫶 she's the canvas, she's the moment
• size — the maximum amount of data to process ⭐ the vibe check on how much we're allowed to do

---

🧚 DESCRIPTION 🧚

This routine dumps the NVME + SCSI statistics associated with vport 💀 yes bestie, both of them, together, iconic behavior fr fr

Return Value: This routine returns the amount of bytes that were dumped into buf and will not exceed size 💅 so she will not be overflowing on your watch, periodt.
