dtrace on a kernel module _init()
...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...
