zfcp_dbf_scsi_nullcmnd(9)

💅 zfcp_dbf_scsi_nullcmnd(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — yes, the actual kernel API manual, and yes, this page is a whole little baddie about tracing a NULLify of a SCSI command. main character energy only 🎀

---

🌸 NAME 🌸

zfcp_dbf_scsi_nullcmnd — trace NULLify of SCSI command in dev/tgt-reset. so like... the receipts when a SCSI command gets nulled out during a device/target reset. iykyk 💅

---

✨ SYNOPSIS ✨

void zfcp_dbf_scsi_nullcmnd (struct scsi_cmnd *scmnd , struct
       zfcp_fsf_req *fsf_req );

it's giving void — nothing comes back, bestie, it just does the thing and dips 💖

---

🦋 ARGUMENTS 🦋

• scmnd — the SCSI command that was NULLified. yep, the actual victim of the null-ing 🙈
• fsf_req — the request that owned scmnd. like, whose command this was. the owner, fr fr 👑

👑 SEE ALSO 👑

soooo many sibling functions and structs, and honestly they all ate 🔥 — the whole zfcp_dbf extended family lives in the kernel file ./drivers/s390/scsi/zfcp_dbf.h, and here's every single one of them, no cap:

• struct zfcp_dbf_rec_running(9)
• enum zfcp_dbf_rec_id(9)
• struct zfcp_dbf_rec(9)

that's the whole squad, periodt 🫶 go read them all, they're iconic ⭐

no cap: this one is straight up just tracing/tracing-logging — nothing spicy, nothing dangerous, just the dev/tgt-reset NULLify getting its moment 🌈

and that's the page!! 💜 it lives in ./drivers/s390/scsi, dated October 2026, and honestly? slay ✨ bye bestie, go null some commands responsibly 💅🎀🍓
