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.
