[SCSI] fusion - exposing raid components in mptsas
Suppport for exposing hidden raid components
for sg interface. The sdev->no_uld_attach flag
will set set accordingly.
The sas module supports adding/removing raid
volumes using online storage management application
interface.
This patch rely's on patch's provided to me
by Christoph Hellwig, that exports device_reprobe.
I will post those patch's on behalf of Christoph.
