#     Merge tag 'trace-v4.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing fix from Steven Rostedt:
#      "This fixes an issue with the build system caused by a change that
#       modifies CC_FLAGS_FTRACE. The issue is that it breaks the dependencies
#       and causes "make targz-pkg" to rebuild the entire world"
#     
#     * tag 'trace-v4.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
