scsi_alloc_sdev(9)

✨ scsi_alloc_sdev(9) ✨

okay bestie so we're in the Kernel API Manual today and this one is literally about making a whole new scsi_device out of thin air 🫶 stay with me, it's actually so good.

---

🌸 NAME 🌸

scsi_alloc_sdev — allocate and setup a scsi_Device 💅

---

🎀 SYNOPSIS 🎀

struct scsi_device * scsi_alloc_sdev (struct scsi_target *starget , u64
lun , void *hostdata );

---

🦋 ARGUMENTS 🦋

• starget — the target you wanna allocate a scsi_device for, like, which one, be specific 💖
• lun — which lun. that's the one. that's the lun ✨
• hostdata — usually NULL, and honestly it gets set by ->sdev_init instead, so don't stress 🙈

---

🌈 DESCRIPTION 🌈

So what it does is: allocate, initialize for io, and return a pointer to a scsi_Device. All three. Iconic behavior honestly 👑

It stores the shost, channel, id, and lun in the scsi_Device, and then adds that scsi_Device to the appropriate list. slay, organized, everything in its place 🎀

Return value: a scsi_Device pointer, or NULL on failure 😭 (not the vibe, but it happens).

kay bye ily, this came from the ./drivers/scsi girlies, dated October 2026, and yes it's still called scsi_alloc_sdev(9) in case you forgot already 🍓💅
