Add a new ACPI hotplug profile flag, demand_offline, such that if set for the given ACPI device object's scan handler, it will cause acpi_scan_hot_remove() to check if that device object's physical companions are offline upfront and fail the hot removal if that is not the case. That flag will be useful to overcome a problem with containers on some system where they can only be hot-removed after some cleanup operations carried out by user space, which needs to be notified of the container hot-removal before the kernel attempts to offline devices in the container. In those cases the current implementation of acpi_scan_hot_remove() is not sufficient, because it first tries to offline the devices in the container and only if that is suffcessful it tries to offline the container itself. As a result, the container hot-removal notification is not delivered to user space at the right time. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |
