  - In the Linux kernel, the following vulnerability has been resolved: perf trace: Really free the
    evsel->priv area In 3cb4d5e00e037c70 (perf trace: Free syscall tp fields in evsel->priv) it only was
    freeing if strcmp(evsel->tp_format->system, syscalls) returned zero, while the corresponding
    initialization of evsel->priv was being performed if it was _not_ zero, i.e. if the tp system wasn't
    'syscalls'. Just stop looking for that and free it if evsel->priv was set, which should be equivalent.
    Also use the pre-existing evsel_trace__delete() function. This resolves these leaks, detected with: $ make
