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
