Author: dchagin Date: Sun Mar 8 08:47:09 2015 New Revision: 279775 URL: https://svnweb.freebsd.org/changeset/base/279775 Log: The latest cp tool is trying to use the btrfs clone operation that is implemented via ioctl interface. First of all return ENOTSUP for this operation as a cp fallback to usual method in that case. Secondly, do not print out the message about unimplemented operation.
