#     
#     Pull ftrace sh build fix from Steven Rostedt:
#      "It appears that the zero-day bot did find a bug in my sh build.
#     
#       And that I didn't have the bad code in my config file when I cross
#       compiled it, although there are a few other errors in sh that makes it
#       not build for me, I missed that I added one more"
#
