    vfs_vnops.c: Change the error return from ENOSYS to EOPNOTSUPP
    
    When the COPY_FILE_RANGE_CLONE flag argument is provided to
    copy_file_range(2), it will return failure if block cloning
    is not supported by the underlying file system.
    
    This patch changes the errno returned for this failure from
    ENOSYS to EOPNOTSUPP.

VOP_COPY_FILE_RANGE")
