Source code changes of the file "lib/crypto_backend/crypto_cipher_kernel.c" between
cryptsetup-2.3.6.tar.xz and cryptsetup-2.4.0.tar.xz

About: cryptsetup is a utility used to conveniently setup disk encryption based on the dm-crypt kernel module. These include plain dm-crypt volumes, LUKS volumes, loop-AES and TrueCrypt compatible format.
