Ned Bass 00ba7ef900 Give ENOTSUP a valid user space error value
The ZFS module returns ENOTSUP for several error conditions where an operation
is not (yet) supported.  The SPL defined ENOTSUP in terms of ENOTSUPP, but that
is an internal Linux kernel error code that should not be seen by user
programs.  As a result the zfs utilities print a confusing error message if an
unsupported operation is attempted:

    internal error: Unknown error 524
    Aborted

This change defines ENOTSUP in terms of EOPNOTSUPP which is consistent with
user space.

README.markdown

The Solaris Porting Layer (SPL) is a Linux kernel module which provides many of the Solaris kernel APIs. This shim layer makes it possible to run Solaris kernel code in the Linux kernel with relatively minimal modification. This can be particularly useful when you want to track upstream Solaris development closely and dont want the overhead of maintaining a large patch which converts Solaris primitives to Linux primitives.

To build packages for your distribution:

$ ./configure
$ make pkg

Full documentation for building, configuring, and using the SPL can be found at: http://zfsonlinux.org
