-/**
- * SECTION:cache
- * @title: Cache
- * @short_description: basic routines to work with libblkid cache
- *
- * Block device information is normally kept in a cache file blkid.tab and is
- * verified to still be valid before being returned to the user (if the user has
- * read permission on the raw block device, otherwise not).  The cache file also
- * allows unprivileged users (normally anyone other than root, or those not in the
- * "disk" group) to locate devices by label/id.  The standard location of the
- * cache file can be overridden by the environment variable BLKID_FILE.
- *
- * In situations where one is getting information about a single known device, it
- * does not impact performance whether the cache is used or not (unless you are
- * not able to read the block device directly).  If you are dealing with multiple
- * devices, use of the cache is highly recommended (even if empty) as devices will
- * be scanned at most one time and the on-disk cache will be updated if possible.
- * There is rarely a reason not to use the cache.
- *
- * In some cases (modular kernels), block devices are not even visible until after
- * they are accessed the first time, so it is critical that there is some way to
- * locate these devices without enumerating only visible devices, so the use of
- * the cache file is required in this situation.
