When the script is terminated the counts are printed for each process that allocated pages while the script was running. The mmfilepage.stp script is useful in debugging leaks in the mapped file regions of a process. +test_check: stap -p4 mmfilepage.stp +test_installcheck: stap mmfilepage.stp -c "sleep 1" |
