lpfc_sli4_fcf_pri_list_add(9)

📦 version 7.3.1, in nixpkgs unstable

💅 lpfc_sli4_fcf_pri_list_add(9) — yeah it's a kernel manpage bestie

okay so real talk, this page is from the Kernel API Manual and it's all about lpfc_sli4_fcf_pri_list_add — a little function that slots an FCF record into a priority list. it's giving "niche driver internals that only three people on earth need", but we're gonna learn it anyway because that's just who we are 💖

✨ NAME ✨

lpfc_sli4_fcf_pri_list_add —

and that's it. that's the whole NAME section. no one-liner. no description. it's giving mysterious. main character energy with zero exposition 🫶 (the original page literally leaves it blank, so we're leaving it blank too. iconique.)

🌸 SYNOPSIS 🌸

int lpfc_sli4_fcf_pri_list_add (struct lpfc_hba *phba , uint16_t
fcf_index , struct fcf_record *new_fcf_record );

literally just three args and an int coming back at you ✨

🎀 ARGUMENTS 🎀

  • phba — pointer to lpfc hba data structure. that's the host bus adapter, bestie, say it with me 🦋
  • fcf_index — the index of the fcf record to add. very demure, very index-y.
  • new_fcf_record — pointer to a new FCF record. and ok this one has lore, so buckle up 🌈 this routine checks the priority of the fcf_index to be added. so:
    • if it's a lower priority than the current head of the fcf_pri list, then it gets added to the list in the right order ✨
    • if it's the same priority as the current head of the list, then it's added to the head of the list and its bit in the rr_bmask is set 💅
    • if the fcf_index to be added is of a higher priority than the current head of the list, then the rr_bmask is cleared, its bit is set in the rr_bmask, and it's added to the head of the list 👑
so like… lower = sorted in place, same = front of the line + bit on, higher = wipe the mask, set the bit, front of the line. three whole vibes. no cap 🔥

⭐ RETURN ⭐

0=success 1=failure

zero means slay, one means 😭. that's the whole spectrum.

👑 SEE ALSO 👑

first up, the kernel file where all this lives:

  • Kernel file ./drivers/scsi/lpfc/lpfc_hbadisc.c

and then a frankly unhinged amount of friends — honestly this is giving "followed by 51 of my closest mutuals":

heads up bestie: lpfc_unregister_fcf(9) really does show up twice in the original list. that's not me being messy, that's the manpage being messy. we keep it exactly as it is 🙈

and that's the whole page 🧚 ok bye, this came from ./drivers/scsi/lpfc and it's dated October 2026 — so yes, it's from the future, and yes, the future still has FCF priority lists 💜 periodt.
