| 10 | Enable encryption of files and directories. This | |
| 11 | feature is similar to ecryptfs, but it is more memory | |
| 12 | efficient since it avoids caching the encrypted and | |
| 643fa961 CR |
13 | decrypted pages in the page cache. Currently Ext4, |
| 14 | F2FS and UBIFS make use of this feature. | |
