+ This driver is used for tagging enterprise files.
+ It is part of the Per-File-Encryption (PFE) feature.
+ The driver is tagging files when created by
+ registered application.
+ Tagged files are encrypted using the dm-req-crypt driver.

+ * Per-File-Tagger (PFT).
+ *
+ * This driver tags enterprise file for encryption/decryption,
+ * as part of the Per-File-Encryption (PFE) feature.
+ *
+ * Enterprise registered applications are identified by their UID.
+ *
+ * The PFT exposes character-device interface to the user-space application,
+ * to handle the following commands:
+ * 1. Update registered applications list
+ * 2. Encryption (in-place) of a file that was created before.
+ * 3. Set State - update the state.
+ *
+ * The PFT exposes kernel API hooks that are intercepting file operations
+ * like create/open/read/write for tagging files and also for access control.
+ * It utilizes the existing security framework hooks
+ * that calls the selinux hooks.
+ *
+ * The PFT exposes kernel API to the dm-req-crypt driver to provide the info
+ * if a file is tagged or not. The dm-req-crypt driver is doing the
+ * actual encryption/decryptiom.
+ *
+ * Tagging the file:
+ * 1. Non-volatile tagging on storage using file extra-attribute (xattr).
+ * 2. Volatile tagging on the file's inode, for fast access.
