dtrace discuss - Sep 2005 - dtrace on a kernel module _init()

I''m looking for an easy way to use dtrace on _init() for a kernel
module but hitting some roadblocks.

This doesn''t work:
::xxx:_init
{
        self->follow=1;
}
:::_fini
{
        self->follow=0;
}

Because there''s no "xxx" when dtrace runs.  The best way I
can see is to use fbt:modinstall:entry, tell dtrace about the modctl struct and
match by the name of the module.

Can we have a new dtrace provider in modctl.c and friends to make this task a
bit simpler?  Or am I missing something else that''s obvious?

Whilst this would appear to fall under the anonymous tracing paradigm, I
don''t see why I should have to reboot to debug the _init() of a module
that loads well after boot or is optional.
