shost_for_each_device(9)

💅 shost_for_each_device ✨

okay bestie, welcome to the Kernel API Manual — this one's a little iterator that's literally the main character of your SCSI host loop 🎀

---

🌸 NAME 🌸

shost_for_each_device — iterate over all devices of a host 💫

---

✨ SYNOPSIS ✨

shost_for_each_device (sdev , shost );

---

🫶 ARGUMENTS 🫶

• sdev — the struct scsi_device to use as a cursor 👀 (yes, it's your lil pointer-bestie that walks the list)
• shost — the struct scsi_host to iterate over 🦋 (this is the host whose devices you're gonna meet)

---

💖 DESCRIPTION 💖

So this is an iterator that returns each device attached to shost. Like, every single one, one at a time, slay 🎀

Here's the tea though: this loop takes a reference on each device and releases it at the end — so the refcounting is handled for you, no cap 🙈

⚠️ But if you break out of the loop early, the loop never gets to the end, so you must call scsi_device_put(sdev) yourself. Fr fr, don't forget, or that reference is just gonna sit there 💀

okay that's the whole page, periodt 💅 this lil gem lives in ./include/scsi and the version stamp says October 2026 — go forth and iterate responsibly, bestie 👑💜
