💖 zfcp_dbf_scsi_eh(9) — a Kernel API Manual moment 💖

okay so bestie, we're diving into zfcp_dbf_scsi_eh(9) and honestly? she's a whole vibe. this is the kernel doc for her, straight out of the manual, no cap. let's get into it 🎀

✨ NAME ✨

zfcp_dbf_scsi_eh — the trace event for the special-case moments of scsi_eh callbacks. like, not every day is a normal day, and this function is the one that shows up for the plot twists 🦋

🌸 SYNOPSIS 🌸

void zfcp_dbf_scsi_eh (char *tag , struct zfcp_adapter *adapter ,
unsigned int scsi_id , int ret );

that's the whole signature, literally right there. look at her go 💅

🫶 ARGUMENTS 🫶

  • tag — the identifier for the event. think of it as the event's little name tag at the party ✨
  • adapter — pointer to the zfcp adapter, serving as the context for this event. she's the main character energy that gives everything around her meaning 💜
  • scsi_id — the SCSI ID/target, there to indicate the scope of the task management function (TMF). yes, TMF. iconic acronym, no notes 👑
  • ret — the return value of the calling function. the receipts, basically. we love a function that keeps them 🧾

🦋 DESCRIPTION 🦋

so here's the tea, bestie: this SCSI trace variant does not depend on any of these — not scsi_cmnd, not zfcp_fsf_req, not scsi_device. none of them. she's independent, she's self-sufficient, she doesn't need that baggage 😭✨

fr fr, that's the whole point of this variant — no dependencies on those three. periodt.

🌈 SEE ALSO 🌈

the whole friend group, gathered for you 🫶 — starting with the kernel file ./drivers/s390/scsi/zfcp_dbf.c, and then:

like, the entire squad. go say hi 💕

and that's the page, bestie!! sourced from ./drivers/s390/scsi, dated October 2026, and yes she signs off as zfcp_dbf_scsi_eh(9) because she knows exactly who she is 💅✨ slay, go read some kernel code, ily 🎀💖
