NAME

       reset-ftrace - reset state of ftrace, disabling all tracing. Written for Linux ftrace.

SYNOPSIS

       reset-ftrace [-fhq]

DESCRIPTION

       This resets the state of various ftrace files, and shows the before and after state.

       This  may  only  be  of  use  to  ftrace  hackers who, in the process of developing ftrace
       software, often get the subsystem into a partially active state, and would  like  a  quick
       way  to  reset  state.  Check the end of this script for the actually files reset, and add
       more if you need.

       WARNING: Only use this if and when you are sure that there  are  no  other  active  ftrace
       sessions on your system, as otherwise it will kill them.

REQUIREMENTS

       FTRACE CONFIG.

OPTIONS

       -f     Force. If the ftrace lock file exists (/var/tmp/.ftrace-lock), delete it.

       -h     Print usage message.

       -q     Quiet. Run, but don't print any output.

EXAMPLES

       Reset various ftrace files:
              # reset-ftrace
