#     
#     Pull tracing fix from Steven Rostedt:
#      "Some of the ftrace internal events use a zero for a data size of a
#       field event. This is increasingly important for the histogram trigger
#       work that is being extended.
#     
#       While auditing trace events, I found that a couple of the xen events
#       were used as just marking that a function was called, by creating a
#       static array of size zero. This can play havoc with the tracing
#       features if these events are used, because a zero size of a static
#       array is denoted as a special nul terminated dynamic array (this is
#       what the trace_marker code uses). But since the xen events have no
#       size, they are not nul terminated, and unexpected results may occur.
#     
#       As trace events were never intended on being a marker to denote that a
#       function was hit or not, especially since function tracing and kprobes
#       can trivially do the same, the best course of action is to simply
#       remove these events"
