Oops, I forgot the closing }.  First, do "dtrace -l | grep _gone_in" to make
sure dtrace is loaded.  You should see something like this:

# dtrace -l | grep _gone_in
87003        fbt            kernel                          _gone_in entry
87004        fbt            kernel                          _gone_in return
98682        fbt            kernel                      _gone_in_dev entry
98683        fbt            kernel                      _gone_in_dev return

Then this should work:

# dtrace -n 'fbt::_gone_in:entry { @counts[curthread->td_proc->p_comm] = count() }'
dtrace: description 'fbt::_gone_in:entry ' matched 1 probe
