zfcp_qdio_sbals_from_sg(9)

💅 NAME 💅

zfcp_qdio_sbals_from_sg — bestie, this one fills SBALs from a scatter-gather list ✨

So like, quick manual, manual name zfcp_qdio_sbals_from_sg(9) in the Kernel API Manual — we're doing kernel internals today and honestly? iconic of us 🎀

---

🌸 SYNOPSIS 🌸

int zfcp_qdio_sbals_from_sg (struct zfcp_qdio *qdio , struct
zfcp_qdio_req *q_req , struct scatterlist *sg );

That's the whole vibe check right there — it takes three pointers and hands you back an int, no cap 🫶

---

💖 ARGUMENTS 💖

• qdio — pointer to struct zfcp_qdio, literally just the qdio struct pointer, she's the main character here 👑
• q_req — pointer to struct zfcp_qdio_req, another pointer, another struct, we love a consistent theme 💅
• sg — the scatter-gather list, and yes it's a list, hence the name, iykyk 🌈

---

🔥 RETURN 🔥

Zero. Or -EINVAL on error 😭 — that's it, that's the whole return story, zero is the slay outcome and -EINVAL is the "something went wrong bestie" outcome 💀

🦋 SEE ALSO 🦋

Kernel file ./drivers/s390/scsi/zfcp_qdio.c — and the whole friend group:

• zfcp_qdio_sbal_get(9)

• zfcp_qdio_allocate(9)
• zfcp_qdio_close(9)
• zfcp_qdio_open(9)
• zfcp_qdio_siosl(9)

Go read those next, they're all in the same ./drivers/s390/scsi directory and they're all lowkey obsessed with qdio 💜
