However, the OS doesn't believe the SSDs unless they are explicitly whitelisted. Acked-by: Martin K.

If not, then we can end up either prematurely completing the internal tag (since it's not set in the hw mask), or simply flag an error: ata2: illegal qc_active transition (100000000->00000001) If the internal tag is set, then swap that with the hardware tag in this case before comparing with what the hardware reports.
