💅 lpfc_idiag_extacc_drivr_get(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a kernel function page, and honestly? It's giving "small but mighty." Let's get into it ✨

---

🌸 NAME 🌸

lpfc_idiag_extacc_drivr_get — the one that gets driver extent information. Iconic, lowkey does exactly what it says on the tin 💖

---

🦋 SYNOPSIS 🦋

int lpfc_idiag_extacc_drivr_get (struct lpfc_hba *phba , char *pbuffer ,
int len );

---

🎀 ARGUMENTS 🎀

• phba — pointer to the lpfc hba data structure. Your main character struct, fr fr 🫶
• pbuffer — pointer to internal buffer. The little data-holder bestie.
• len — length into the internal buffer data has been copied. Like, how much stuff already made it in there 💅

---

✨ DESCRIPTION ✨

So this routine is literally here to get the driver extent information. That's it, that's the vibe. No cap, it's a getter and it's serving its purpose 🌈

---

👑 RETURN 👑

Returns the overall length of the data read into the internal buffer — so you know exactly how much got copied in. Numbers, slay 💯
