The commit 643fa9612bf1 ("fscrypt: remove filesystem specific
build config option") removed modular support for fs/crypto. This
causes the Crypto API to be built-in whenever fscrypt is enabled.
This makes it very difficult for me to test modular builds of
the Crypto API without disabling fscrypt which is a pain.
As fscrypt is still evolving and it's developing new ties with the
fs layer, it's hard to build it as a module for now.
However, the actual algorithms are not required until a filesystem
is mounted. Therefore we can allow them to be built as modules.

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.
