Usable device filter is responsible for filtering out unusable DM devices. The filter has 3 modes of operation: - FILTER_MODE_NO_LVMETAD: When this mode is used, we check DM device usability by looking: - whether device is empty - whether device is blocked - whether device is suspended (only on devices/ignore_suspended_devices=1) - whether device uses an error target - whether device name/uuid is reserved - FILTER_MODE_PRE_LVMETAD: When this mode is used, we check DM device usability by looking: - whether device is empty - whether device is suspended (only on devices/ignore_suspended_devices=1) - whether device uses an error target - whether device name/uuid is reserved - FILTER_MODE_POST_LVMETAD: When this mode is used, we check DM device usability by looking: - whether device is blocked - whether device is suspended (only on devices/ignore_suspended_devices=1) These modes will be used by subsequent patch to create different instances of this filter, depending on lvmetad use.
