📦 version 7.3.1, in nixpkgs unstable

💅 i91u_queuecommand_lck — ok so hear me out bestie

this one lives in the Kernel API Manual, page i91u_queuecommand_lck(9), and it's literally the "can u take this command rn" girlie of the initio driver 🌸

✨ NAME ✨

i91u_queuecommand_lck — queue a new command if possible 🎀

✨ SYNOPSIS ✨

enum scsi_qc_status i91u_queuecommand_lck (struct scsi_cmnd *cmd );

✨ ARGUMENTS ✨

  • cmd — the SCSI command block, handed down from the mid layer 🫶 like it's coming straight from upstairs and she's the one who has to deal with it

✨ DESCRIPTION ✨

okay so what she does is: she attempts to queue a new command with the host adapter 💫 that's the whole gig. no cap.

  • if it works out? she returns zero 😌 slay, iconic, no notes.
  • if it doesn't? she flags a host busy condition instead 🙈 which is basically her texting the mid layer "bestie not rn" — and that makes the mid layer come back and call us again later with the same command. fr fr, it's a whole callback situation 💀

so yeah. zero = we ate. host busy = try again later, she's booked. 💅

lowkey the "we'll call you again later" part is doing a LOT of work here, so don't be out here assuming it's a hard fail. it's a vibe check pending.

🌈 SEE ALSO 🌈

she does not ride alone, she runs with a whole crew — all of these live in the kernel file ./drivers/scsi/initio.c:

mwah 💜 that's the whole page, bestie — courtesy of the source living at ./drivers/scsi, stamped October 2026. go forth and queue responsibly ✨🎀
