32 /**
33  * DTrace support macros for the linuxulator.
34  *
35  * Some wrapper macros to make it more easy to handle the linuxulator
36  * providers and to allow to make the name depend upon the bitsize.
37  *
38  * Basically this is the same as the normal SDT macros in sys/sdt.h. The
39  * difference is that the provider name is automatically inserted, and
40  * we do not use a different name for the probe-description.
