  support

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux package in Ubuntu:

Status in linux source package in Trusty:

Bug description:
  The ubuntu_ftrace_smoke_test is failing on Trusty ARM64.

  It looks like it will need the following configs for get it work:
  CONFIG_FUNCTION_TRACER=y 
  CONFIG_FUNCTION_GRAPH_TRACER=y 
  CONFIG_STACK_TRACER=y 
  CONFIG_DYNAMIC_FTRACE=y 

  ftrace is useful for debugging. We should enable it.
