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

| # Filesystems supporting encryption must select this if FS_ENCRYPTION. This |
| # allows the algorithms to be built as modules when all the filesystems are. |
