💅 lpfc_sdev_init(9) — Kernel API Manual

Okay so bestie, welcome to the glow-up of lpfc_sdev_init! This is the scsi_host_template sdev_init entry point, and it's giving main character energy. Let's get into it. 🦋

✨ NAME ✨

lpfc_sdev_init — scsi_host_template sdev_init entry point

---

🎀 SYNOPSIS 🎀

int lpfc_sdev_init (struct scsi_device *sdev );

---

🌸 ARGUMENTS 🌸

• sdev — Pointer to scsi_device. (Like, it's the device we're initializing, bestie! 💖)

---

💅 DESCRIPTION 💅

Okay so here's the tea ☕: This routine populates the cmds_per_lun count + 2 scsi_bufs into this host's globally available list of scsi buffers — no cap. This routine also makes sure the scsi buffer is not allocated more than the HBA limit conveyed to midlayer, periodt. This list of scsi buffer exists for the lifetime of the driver, fr fr. 🫶

Return codes:

• non-0 — Error 😭
• 0 — Success ✨
