mpi3mr_host_tag_for_scmd(9)

📦 version 7.3.1, in nixpkgs unstable

💅 mpi3mr_host_tag_for_scmd — Kernel API Manual, section 9 🎀

okay so real talk, bestie: this page comes straight out of the Kernel API Manual, and it's page mpi3mr_host_tag_for_scmd(9). It's one of those tiny little helper functions in the mpi3mr driver that does exactly one job and does it slayfully. Nothing scary here, I promise. 🫶

✨ NAME ✨

mpi3mr_host_tag_for_scmd — get the host tag for a scmd 👑

🦋 SYNOPSIS 🦋

u16 mpi3mr_host_tag_for_scmd (struct mpi3mr_ioc *mrioc , struct
       scsi_cmnd *scmd );

🌸 ARGUMENTS 🌸

  • mrioc — the adapter instance reference, aka which controller we're talking about 💜
  • scmd — the SCSI command reference itself, the little guy we want a tag for 🎀

🔥 DESCRIPTION 🔥

So what does it actually do? It calculates the host tag based on the block tag for a given scmd. That's it. That's the whole vibe. Iconic, minimal, no notes. ✨

⭐ RETURN ⭐

It hands you back a valid host tag — or, if things didn't work out, MPI3MR_HOSTTAG_INVALID. 😭 No cap, that's the entire contract.

🌈 SEE ALSO 🌈
