ipr_queuecommand(9)

💖 NAME 💖

ipr_queuecommand(9) — queue a mid-layer request. Yep bestie, this is the Kernel API Manual page for that exact function, and it's giving “small function, big queue energy.” 💅

---

🌸 SYNOPSIS 🌸

enum scsi_qc_status ipr_queuecommand (struct Scsi_Host *shost , struct scsi_cmnd *scsi_cmd );

---

🎀 ARGUMENTS 🎀

• shost — scsi host struct 🫶
• scsi_cmd — scsi command struct ✨

---

🦋 DESCRIPTION 🦋

This function queues a request generated by the mid-layer. That's the whole vibe: mid-layer request goes in, queueing happens. Iconic behavior, no notes. 👑

Return value tea ☕:

• 0 on success 🎉
• SCSI_MLQUEUE_DEVICE_BUSY if device is busy 😭
• SCSI_MLQUEUE_HOST_BUSY if host is busy 💀

Bestie, those busy statuses are not a “try again never” situation in the page — they're literally the listed return values, so keep them exact. Periodt.
