fc_vport_set_state(9)

✨ fc_vport_set_state ✨

Okay bestie, you found the fc_vport_set_state(9) page in the Kernel API Manual and honestly? It's a little cutie. 🎀 Let me give you the whole rundown, group-chat style.

---

🌸 NAME 🌸

fc_vport_set_state — this is the function you call to set a vport's state. It saves the old state, except for the transitory states of initializing and sending the ELS traffic to instantiate the vport on the link. Not me being precise about exceptions 💅

---

🦋 SYNOPSIS 🦋

void fc_vport_set_state (struct fc_vport *vport , enum fc_vport_state
new_state );

---

✨ ARGUMENTS ✨

• vport — the virtual port whose state is changing, like the main character of this whole operation 👑
• new_state — the new state, obviously. the glow-up destination 💖

---

💜 DESCRIPTION 💜

Lowkey important caveat first: this function assumes the driver has surrounded it with the proper locking so the state change stays coherent. No cap, that's on the driver — the function itself is not out here doing its own locking. 🙈

---

🌈 SEE ALSO 🌈

• Kernel file ./include/scsi/scsi_transport_fc.h
• fc_remote_port_chkready(9)

---

fr fr read the locking note again. coherent state change is the vibe, and the driver brings the locks. 🫶

Okay that's the whole thing bestie, you ate that. 💅✨ This little gem lives in ./include/scsi, dated October 2026, and it's part of the Kernel API Manual. mwah, go forth and set those states responsibly 🎀🦋
