- * The purpose of these functions is to try to get and set the proper
- * file permissions, SELinux contexts, owner, and group so that these
- * files are accessible when we boot up to normal Android via MTP and to
- * file manager apps. During early boot we try to read the contexts and
- * owner / group info from /data/media or from /data/media/0 and store
- * them in static variables. From there, we'll try to set the same
- * contexts, owner, and group information on most files we create during
- * operations like backups, copying the log, and MTP operations.
