The fix posted exclusively changes the behavior of AHCI devices; however the locking changes that jostled the AHCI bug loose could in theory jostle loose some bugs in other devices, too.
I don't think it is possible that the fix for AHCI would have any impact on virtio-scsi devices.
If you're seeing issues in virtio-scsi, I'd make a new writeup in a new LP.
