@ahl @bcantrill Thanks for not waiting until after your break to post it, that was a doozy.

Listeners should note this mentions use of #dtrace not just through its anonymous tracing feature, but in fact through its speculative tracing feature as well.

Starting to get back into illumos/arm64. Current weekend project is getting DTrace working. Some initial progress:

# dtrace -n 'profile-997{@[stack()] = count();}' | tail
dtrace: description 'profile-997' matched 1 probe
genunix`taskq_thread+0x2e8
genunix`thread_exit
6

genunix`thread_exit
3779

Working fbt provider will be a bit harder...
