lpfc_debugfs_ioktime_data(9)

✨ lpfc_debugfs_ioktime_data ✨

okay so this is a page from the Kernel API Manual — yes, the big serious kernel one 💅 — and it's all about lpfc_debugfs_ioktime_data, a lil routine from the lpfc driver. group chat, settle in, it's short and sweet 🎀

---

🌸 NAME 🌸

lpfc_debugfs_ioktime_data — Dump target node list to a buffer 🫶

---

✨ SYNOPSIS ✨

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

like, that's the whole signature bestie, it takes three things and hands you back an int 👑

---

🎀 ARGUMENTS 🎀

• vport — the vport you're pulling target node info out of 💖 this is literally the star of the show
• buf — the buffer where the log gets dumped, your data goes here, no cap
• size — the maximum amount of data to process 🔥 like, the ceiling, the limit, the "don't go past this" line

---

🦋 DESCRIPTION 🦋

so what does it actually do? this routine dumps the NVME statistics associated with vport ✨ that's the vibe.

Return Value: it returns the amount of bytes that were dumped into buf, and it will not exceed size — so it's polite, it respects your buffer budget 🙈
