lpfc_sli4_fc..._index_clear(9)

💅 lpfc_sli4_fcf_rr_index_clear — okay bestie, listen

So this one lives in the Kernel API Manual, section 9 (iykyk, kernel functions), and the page header literally says lpfc_sli4_fc..._index_clear(9) — truncated with dots and everything, no cap, that's just how it's printed. The full-grown name is down in NAME and it's a mouthful.

✨ NAME ✨

lpfc_sli4_fcf_rr_index_clear — clears the bmask from the eligible fcf record index 🎀

Like, that's the whole job. It takes a bit and it un-takes it. Slay.

---

🌸 SYNOPSIS 🌸

void lpfc_sli4_fcf_rr_index_clear (struct lpfc_hba *phba , uint16_t
fcf_index );

Returns void, so like… don't go looking for a return value, she gives you nothing back and that's the vibe 💀

---

🦋 ARGUMENTS 🦋

• phba — pointer to lpfc hba data structure. Your HBA. Your main character. Show some respect 🫶
• fcf_index — index into the FCF table to 'clear'. Note the scare quotes around clear — that's the manpage being cute, not me, I'm just reporting the facts 💖

---

👑 DESCRIPTION 👑

Okay so picture this: this routine clears the FCF record index from the eligible bmask for roundrobin failover search. That's the whole errand. She goes in, she wipes the bit, she leaves.

But — and this is the important part, don't skip it — before clearing that bit, she checks to make sure the index does not go beyond the range of the driver allocated bmask dimension. So she's not just blindly yeeting bits out here, she's doing a lil vibe check on the index first. Bounds-checked queen ✨

no out-of-range nonsense on her watch, fr fr 🔥

🎀 the sign-off 🎀

This lil masterpiece comes from ./drivers/scsi/lpfc and is dated October 2026, and the footer calls her lpfc_sli4_fc..._index_clear(9) — same truncated name, same page, iconic behaviour honestly 💜

Anyway bestie, go clear that bit. Bounds-checked. Bit-wise. Slay ✨🌷
