scsi_get_internal_cmd(9)

💅 scsi_get_internal_cmd (9) — Kernel API Manual ✨

Okay so bestie, welcome to the manual page for scsi_get_internal_cmd — it's a kernel API thing, and honestly? It's giving "small function, big responsibility." Let's get into it 🫶

---

🌸 NAME 🌸

scsi_get_internal_cmd — Allocate an internal SCSI command. That's it, that's the vibe ✨

---

🎀 SYNOPSIS 🎀

struct scsi_cmnd * scsi_get_internal_cmd (struct scsi_device *sdev ,
enum dma_data_direction data_direction , blk_mq_req_flags_t flags );

Literally the whole signature, character for character, no cap 💅

---

🦋 ARGUMENTS 🦋

• sdev — the SCSI device you're grabbing the command from. Like, which device, bestie? This one.
• data_direction — the data direction for the command you just allocated. Gotta know which way the bytes are flowing 🌈
• flags — your request allocation flags, for example BLK_MQ_REQ_RESERVED or BLK_MQ_REQ_NOWAIT. Pick your little permission slips wisely 💖

---

👑 DESCRIPTION 👑

So what does it do? It allocates a SCSI command for internal LLDD use. That's the whole thing — a fresh struct scsi_cmnd * handed to you for LLDD-internal business. Short description, iconic behavior. Periodt ✨
