Passthrough backends like pscsi and user do not support ALUA managment through configfs. You can create groups, but writing to files can cause the kernel crashes. This adds a alua_supported method that backends can override and return False to indicate they do not support ALUA. Signed-off-by: Mike Christie <mchristi@redhat.com>
