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" * tag 'trace-v4.17-rc4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing/x86/xen: Remove zero data size trace events trace_xen_mmu_flush_tlb{_all}
