Created attachment 13144

it
stap -vvvv -DSTAP_TRANS_DEBUGFS output

Output from

  $ sudo mount /sys/kernel/debug -o remount,mode=3D700

  $ stap -vvvv -DSTAP_TRANS_DEBUGFS -e 'probe begin { printf("started\n");
exit(); }'

on stap 4.4 from systemtap-4.4-2.fc33.x86_64=20

I filtered it with=20

  egrep -v '^(Skipping tapset|Processing)'

to reduce irrelevant spam.
