zfcp_unit_sdev_status(9)

💅 zfcp_unit_sdev_status — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual entry for zfcp_unit_sdev_status(9) ✨ this one's short and sweet, so like, hydrate and let's go 🫶

✨ NAME ✨

zfcp_unit_sdev_status — Return zfcp LUN status for SCSI device 🎀

🌸 SYNOPSIS 🌸

unsigned int zfcp_unit_sdev_status (struct zfcp_unit *unit );

that's it. one arg. one return value. main character energy fr fr 👑

🦋 ARGUMENTS 🦋

• unit — the unit you want to look up the SCSI device for 🧚 like, this is the thing you're handing over so the function knows which unit's SCSI device it should go hunting for, iykyk

💖 DESCRIPTION 💖

so here's the vibe check: this function returns the zfcp LUN status field of the SCSI device — but only if the SCSI device for the zfcp_unit actually exists. 💀

and if it doesn't exist? you get 0. that's the whole deal. zero. nothing. the void. 🙈

no cap, that's literally the entire description — sometimes the lore is just that simple ✨

🔥 SEE ALSO 🔥

the kernel file is ./drivers/s390/scsi/zfcp_unit.c and honestly go read it, it's giving homework-but-make-it-cute 📚
