Which reminds me, I need to replace pr_debug() to pr_info() for this
line:
pr_debug("syscall %s metadata not mapped, disabling ftrace event\n",
In trace_syscalls.c (I didn't add that), as a different commit that
changed syscall names for x86 caused all syscall tracepoints to
disappear. And if this was pr_info() and not pr_debug() the one that
made the change would have noticed his change had impact someplace else.
