💅 NAME 💅

scsi_host_set_state — Take the given host through the host state model. ✨ This is from the Kernel API Manual, bestie — we're in kernel API land now. 🫶

---

🦋 SYNOPSIS 🦋

The signature, verbatim, no edits:

int scsi_host_set_state (struct Scsi_Host *shost , enum scsi_host_state
       state );

---

🌸 ARGUMENTS 🌸

• shost — scsi host to change the state of. 💖
• state — state to change to. 🦋

---

🔥 DESCRIPTION 🔥

Okay so the return tea is literally this, and I am quoting it exactly: "Returns zero if unsuccessful or an error if the requested transition is illegal." 😭

So yes: zero if unsuccessful, or an error if the requested transition is illegal. That's the whole description. The illegal transition part is the dramatic one — periodt. 👑
