>   sdt: add support for solaris/illumos style DTRACE_PROBE macros
>   
>   The new macros are implemented in terms of SDT_PROBE_DEFINE and SDT_PROBE.
>   Probes defined in this way will appear under SDT provider named "sdt".
>   Parameter types are exposed via SDT_PROBE_ARGTYPE.
>   This is something that illumos does not have by default.
>   
>   This kind of SDT probes is already present in ZFS code, so those probes
>   will now be available if KDTRACE_HOOKS options is enabled.
>   
>   A potential future illumos compatibility enhancement is to encode a provider
>   name as a prefix in a probe name.
