Pull fscrypt updates from Eric Biggers:
"Some small fixes and cleanups for fs/crypto/:
- Fix ->getattr() for ext4, f2fs, and ubifs to report the correct
st_size for encrypted symlinks
- Use base64url instead of a custom Base64 variant
- Document struct fscrypt_operations"
* tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt:
fscrypt: document struct fscrypt_operations
fscrypt: align Base64 encoding with RFC 4648 base64url
fscrypt: remove mention of symlink st_size quirk from documentation
ubifs: report correct st_size for encrypted symlinks
f2fs: report correct st_size for encrypted symlinks
ext4: report correct st_size for encrypted symlinks
fscrypt: add fscrypt_symlink_getattr() for computing st_size
