Utility functions and control variables which can be used to create standardized CVE patches. The globals are cve_notify_p (non-zero if the patch should be verbose), cve_fix_p (non-zero if the fix should be applied), cve_trace_p (non-zero if only a trace should be run), cve_enabled_p (non-zero if the patch should be enabled). The controls can be changed in /proc/systemtap/MODULE_NAME/* and the recorded prometheus metrics can be viewed in the same directory.
