[dtrace-discuss] ustack() question

[Peter Lawrence]

the Users Guide isn't explicit about what happens when ustack() is called
and there isn't any user address space or stack associated with the
current kernel thread.  It only gives examples where there certainly is,
using the syscall provider.

I have used sched:::off-cpu to see user-stacks at context-switch events,
and it seems to work just fine, but I'm wondering how to put in an
explicit predicate for user-associated kernel threads...?...

thanks
Pete Lawrence.
