Now I see a perf test failure on the vmlinux test:
$ sudo ./perf test -v vmlinux 1: vmlinux symtab matches kallsyms : --- start --- test child forked, pid 4164115 /proc/{kallsyms,modules} inconsistency while looking for "[__builtin__kprobes]" module! /proc/{kallsyms,modules} inconsistency while looking for "[__builtin__kprobes]" module! /proc/{kallsyms,modules} inconsistency while looking for "[__builtin__ftrace]" module!
