2021-07-09usb: drop usb_host_dev_is_scsi_storage hookGerd Hoffmann7-36/+17
Introduce an usb device flag instead, set it when usb-host looks at the device descriptors anyway. Also set it for emulated storage devices, for consistency. Add an inline helper function to check the flag. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Jose R.

2021-07-09meson: fix missing preprocessor symbolsPaolo Bonzini5-9/+7
While most libraries do not need a CONFIG_* symbol because the "when:" clauses are enough, some do. Add them back or stop using them if possible. In the case of libpmem, the statement to add the CONFIG_* symbol was still in configure, but could not be triggered because it checked for "no" instead of "disabled" (and it would be wrong anyway since the test for the library has not been done yet).

backend_defaults property allow users to control if default block properties should be decided with backend information. If it is off, any backend information will be discarded, which is suitable if you plan to perform live migration to a different disk backend. If it is on, a block device may utilize backend information more aggressively.
