sd_zbc_complete(9)

📦 version 7.3.1, in nixpkgs unstable

💅 sd_zbc_complete(9) 💅

okay so bestie, we're in the Kernel API Manual today and the star of the show is sd_zbc_complete — say it with me now 🎀

✨ NAME ✨

sd_zbc_complete — ZBC command post processing. that's it, that's the vibe: the lil cleanup era after a zone command does its thing 🧹✨

🌸 SYNOPSIS 🌸

unsigned int sd_zbc_complete (struct scsi_cmnd *cmd , unsigned int
good_bytes , struct scsi_sense_hdr *sshdr );

look at her go 😭 returns an unsigned int, takes three args, absolutely serving signature 💅

🦋 ARGUMENTS 🦋

  • cmd — the Completed command 🫶 like, the command that just finished, she's done, she's clocked out
  • good_bytes — Command reply bytes 📦 the byte count that came back in the reply, iykyk
  • sshdr — the command sense header 🩺 that's your struct scsi_sense_hdr bestie, the whole sense situation

💖 DESCRIPTION 💖

so this one gets called from sd_done — yeah, she's a callback girlie — and her whole job is handling zone command errors plus keeping the device queue's zone write pointer offset cache up to date 🔥

and yeah the original page spells it cahce 😭 not me pointing that out but like... it's giving typo, we still love her, no cap 🫶

ngl this is post processing duty only — errors and cache updates, that's the whole assignment. don't come for her for anything else 💀
