Allow symbolic links which point to /dev/sgX devices.
Couldn't you send an SG_IO test ioctl over and see if it works? I really
dislike the whole file name magic matching.
You could, but the result would not be what you expect, given that every
/dev/sd* device and more in Linux support it.
What we really need is to stop shoe-horning scsi pass through support
into the block layer. Once we finally get our generic thread offload
facilily there is no need for it anymore at all, scsi-generic can
simplify offload the SG_IO ioctl and be done with it. I even have an
old prototype for this, just waiting for the generic thread offload
to get merged before resurrecting it.
