LEA is a Korean national standard (KS X 3246) and included in the ISO/IEC 29192-2:2019 standard (Information security - Lightweight cryptography - Part 2: Block ciphers). Enable the LEA to be used in block inline encryption. This can be used via blk-crypto-fallback, when using the "inlinecrypt" mount option in fscrypt.
