zfcp_dbf_san_in_els(9)

📦 version 7.3.1, in nixpkgs unstable

💅 zfcp_dbf_san_in_els — like, the Kernel API Manual page, bestie ✨

okay so picture this: you're deep in the kernel docs, right, and you stumble on zfcp_dbf_san_in_els, and you're like "what even is this" — no worries babe, I got you. This is the manual page for the trace event for incoming ELS 🦋 (yes, that ELS, the Fibre Channel Extended Link Services kind, iykyk). It lives in the Kernel API Manual, and we're gonna go through it together, section by section, no skipping, periodt.

✨ NAME ✨

zfcp_dbf_san_in_els — it's literally the trace event for incoming ELS 💫 that's the whole vibe, that's the whole name.

🎀 SYNOPSIS 🎀

here's the signature, copy it exactly bestie, don't be creative with it:

void zfcp_dbf_san_in_els (char *tag , struct zfcp_fsf_req *fsf );

that's it. that's the function. void return, two args, she's iconic, she's done 💅

🌸 ARGUMENTS 🌸

okay so these are the two things you gotta hand her, and like, they both matter:

  • tag — this is your identifier for the event 🏷️ like a little name tag for the trace entry so you know what's what later. main character labeling energy.
  • fsf — the request containing the received ELS data 📥 she wants the struct zfcp_fsf_req *, and it's gotta be the one carrying the ELS data she just received. no cap, that's where the good stuff lives.

🦋 SEE ALSO 🦋

okay this is the part where I list the whole friend group 💖 because look at all these related functions, and we are NOT leaving anyone out, everyone gets an invite:

like, that's the whole zfcp_dbf ensemble cast and honestly? obsessed 🌈 go read them too, they're all in ./drivers/s390/scsi/zfcp_dbf.c together, one big happy file.

💀 friendly reminder: the manpage source and the functions above are tight — if you're poking around, the Kernel file ./drivers/s390/scsi/zfcp_dbf.c path is where the actual code lives, fr fr.

and that's the whole page bestie!! mwah 🫶 quick lil sign-off for the credits: this gem comes to you from the path ./drivers/s390/scsi, stamped October 2026, and it is, of course, zfcp_dbf_san_in_els(9) 🎀✨💜
