By the way, this also applies to Linux 4.4 on Ubuntu 16.04 because Canonical has decided to backport this change.

[Åke Sandgren]

It might be more consistent to do this the same way that posix_acl_from_xattr and posix_acl_to_xattr are handled, in libcfs/include/libcfs/linux/linux-fs.h

Thanks for the hint! I have updated the patch accordingly.
