🦋 DESCRIPTION 🦋

okay so picture this: we're taking a SCSI WRITE SAME command and translating it into either a DSM TRIM command or an SCT Write Same command 🌈 the way it decides is by checking whether the WRITE SAME command has the UNMAP flag 👑

  • When set — translate it to DSM TRIM ✂️
  • When clear — translate it to SCT Write Same 🫧

that's the whole vibe check. iconic behavior honestly 💀✨
