scsi_add_lun(9)

✨ scsi_add_lun(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a little kernel function called scsi_add_lun, and it's literally the glow-up station for a scsi_device. no cap.

---

🌸 NAME 🌸

scsi_add_lun — allocate and fully initialize a scsi_device 🫶

---

🎀 SYNOPSIS 🎀

int scsi_add_lun (struct scsi_device *sdev , unsigned char *inq_result ,
blist_flags_t *bflags , int async );

that's the whole signature, keep it exactly like that, she's precise 💖

---

🦋 ARGUMENTS 🦋

• sdev — this cutie holds the information that's gonna get stored in the new scsi_device ✨
• inq_result — holds the result of a previous INQUIRY to the LUN 👀 like, the receipts from the last time someone asked
• bflags — the black/white list flag 🖤🤍 yes both, she contains multitudes
• async — 1 if this device is being scanned asynchronously ⚡ (otherwise it's doing the synchronous thing, iykyk)

---

💜 DESCRIPTION 💜

So basically: initialize the scsi_device sdev. 🫶 And optionally set fields based on the values in *bflags — only if you pass them, no pressure, she's flexible like that 💅

---

🌈 RETURN 🌈

• SCSI_SCAN_NO_RESPONSE — could not allocate or setup a scsi_device 😭 it's giving flop era, no device for you
• SCSI_SCAN_LUN_PRESENT — a new scsi_device was allocated and initialized 👑 main character energy, she ate
