📦 version 7.3.1, in nixpkgs unstable

💅 qla4xxx_update_isid(9) — like, the Kernel API Manual energy ✨

okay so bestie, buckle up 🎀 this one lives in the Kernel API Manual, and it's a little kernel function that does one very specific thing and does it iconically. let's get into it 💖

🌸 NAME 🌸

qla4xxx_update_isid — compare ddbs and updated isid

like literally, its whole personality is comparing ddbs and updating the isid. slay.

✨ SYNOPSIS ✨

int qla4xxx_update_isid (struct scsi_qla_host *ha , struct list_head
*list_nt , struct dev_db_entry *fw_ddb_entry );

that's the whole signature, no cap — three args, returns an int. handle it 🫶

🦋 ARGUMENTS 🦋

  • ha — pointer to host adapter structure. yes queen, the host adapter, the main character of the show 👑
  • list_nt — list of nt target. that's it, that's the whole description, we love a low-maintenance parameter 💀
  • fw_ddb_entry — firmware ddb entry. the firmware's very own ddb entry, no notes 🌸

💜 DESCRIPTION 💜

okay so here's the vibe: this routine update isid if ddbs have same iqn, same isid and different IP addr. all three conditions, bestie — same iqn, same isid, different IP addr — that's the magic combo 🔥

and it returns QLA_SUCCESS if isid is updated. literally that's the deal. iconic behavior, no notes ✨

ngl the triple-condition thing is the whole point — miss one and this thing just doesn't do the update. vibe check your ddbs first 💅

and that's the tea 🍓 this page ships straight out of ./drivers/scsi/qla4xxx, dated October 2026 — so yeah, mark your calendars bestie, that's the Kernel API Manual era and we're living in it 💜🦋 iykyk 🌈
