Mohamed Khalfella 58e7c13c8f nvme: add opcode filtering for fault injection Currently NVMe fault injection applies to every command routed through nvme_should_fail(), which makes it hard to target a specific command type when reproducing an issue in error-handling paths. Add an "opcode" debugfs attribute alongside the existing "status" and "dont_retry" knobs. It defaults to 0xffff, meaning "match any opcode" and preserving the previous behavior. When set to a valid opcode (<= 0xff), fault injection is only considered for commands whose opcode matches.
