…tries previous udev script just deleted the parent entry when a partition was busy we keep this behavior for local use the "busy marker" is propagated to USB parent
if one of subdevices are locally used (e.g. in sys-usb) the parent is considered busy.

busyattribute handling so a device that's in use (attached or used locally) stays visible in QubesDB with a busy=True marker instead of disappearing entirely, and propagates that marker up to the parent disk and the USB ancestor.xs_mark_busy,xs_mark_usb_busyset busy on the device and on the USB parent.usb_parent_still_in_usescans all sibling devices for either attachment or local use, to decide if the USB busy marker can be cleared.qubes.RefreshBlockDevicesre-triggers udev change events for it and its partitions after detach to force a state refresh from the one place that actually knows the truth (backend's sysfs + mount table), instead of guessing from cache.Open items:
