   4 # Purpose of this script is to show the method used to integrate fscrypt
   5 # sources from the Linux kernel, and the transformations required.
   6 #
   7 # All C files from $LINUX/fs/crypto/ are put under libcfs/libcfs/crypto/.
   8 # File $LINUX/include/linux/fscrypt.h is put in libcfs/include/libcfs/crypto/.
   9 # File $LINUX/include/uapi/linux/fscrypt.h is placed under
  10 # libcfs/include/uapi/linux/.
