zfcp_fsf_close_port(9)

💅 zfcp_fsf_close_port — bestie's guide to closing a port ✨

okay so this is zfcp_fsf_close_port, a little kernel function from the zfcp_fsf files (that's the s390 SCSI Fibre Channel driver, iykyk). It lives in the Kernel API Manual, and honestly? Its whole vibe is "make the close port request, then send it." Short, sweet, main character energy. 🎀

🌸 NAME 🌸

zfcp_fsf_close_port — create and send close port request 🫶

Like, that's literally the job. Create it, send it, done. No cap.

That's the whole signature, bestie — one parameter, returns an int, exactly like it says. 💖

• erp_action — pointer to struct zfcp_erp_action. That's it, that's the one thing you hand it. 🧚
