zfcp_diag_update_xdata(9)

📦 version 7.3.1, in nixpkgs unstable

💫 zfcp_diag_update_xdata 💫

okay so bestie, welcome to the Kernel API Manual page for zfcp_diag_update_xdata(9) — yes the whole page is named after the function, that's just how these things roll, iykyk 🎀

✨ NAME ✨

zfcp_diag_update_xdata — update a diagnostics buffer. that's it, that's the vibe 💅

🌸 SYNOPSIS 🌸

void zfcp_diag_update_xdata (struct zfcp_diag_header *const hdr , const
       void *const data , const bool incomplete );

like, it returns nothing (void, the humble icon) and it takes three things. keep the consts exactly where they are, they're doing main character work 🫶

🦋 ARGUMENTS 🦋

  • hdr — the meta data to update. this is the little header guy getting a glow-up ✨
  • data — data to use for the update. the actual payload, the moment, the substance 💖
  • incomplete — flag stating whether the data in data is incomplete. yes she's a bool, yes she's telling you the truth about whether the data is fully cooked or not 🍓

👑 SEE ALSO 👑

the kernel file doing the heavy lifting lives at ./drivers/s390/scsi/zfcp_diag.c — go say hi to the whole friend group there:

no cap, read them in order and it all clicks 🔥

ngl this one's short and sweet — no warnings, no errors, no exit statuses, just a tidy little update function being iconic 🌈

and that's the page!! 💜 sign-off time: this lil beauty comes from ./drivers/s390/scsi, dated October 2026, filed under zfcp_diag_update_xdata(9) in the Kernel API Manual — the way that this manpage is literally so short and still ate, obsessed 😭🎀
