zfcp_unit_sdev(9)

💖 NAME 💖

okay so bestie, this is zfcp_unit_sdev(9) from the Kernel API Manual, and the whole vibe is: Return SCSI device for zfcp_unit. 🎀

---

✨ SYNOPSIS ✨

struct scsi_device * zfcp_unit_sdev (struct zfcp_unit *unit );

---

🦋 ARGUMENTS 🦋

• unit — the zfcp_unit where to get the SCSI device for. 💅

---

🌸 RETURN 🌸

On success you get a scsi_device pointer, and NULL if there is no SCSI device for this zfcp_unit. That’s the whole return story, no cap. ✨

---

💜 DESCRIPTION 💜

On success, the caller also holds a reference to the SCSI device — and bestie, that reference must be released with scsi_device_put. Not optional, not a maybe, not a “later” thing. 💅

friendly little callback: you got a reference, so you gotta put it back with scsi_device_put. 🫶
