I noticed it on the mailing lists and found this site which wasn't covered. Some background: [1] https://lore.kernel.org/all/CA+55aFwp4iy4rtX2gE2WjBGFL=3DNxMVnoFeHqYa2j= 1dYOMMGqxg@mail.gmail.com/ [2] https://lore.kernel.org/linux-scsi/20260704-b4-scsi-v2-0-7d2d21a810de@k= ernel.org/T/#t I apologize for this messy reply. I thought I had added the context, but I didn't. Best regards, Mahad Ibrahim
