#lfelc ftrace initializes late for tracing kmem events. also can loose events on buffer overuse

#lfelc ftrace is well maintained. But can lose events due to late initialization and can lose evets due to event buffer OVERCOMMIT.

#lfelc raise the trace buffer size is possible, well if you have mem left for that
