Move the code around caching active dm device devno, name and uuid from device_mapper/libdm-iface to dev_cache file - as libdm layer cares about 'decoding' ioctl data from kernel and caching for use by lvm stays within lvm. Introduce: dev_cache_update_dm_devs dev_cache_get_dm_dev_by_devno dev_cache_get_dm_dev_by_uuid Use radix_tree for searching. |
