Now when new refcount_t type and API are finally merged (see include/linux/refcount.h), the following patches convert various refcounters in the tools susystem from atomic_t to refcount_t. By doing this we prevent intentional or accidental underflows or overflows that can led to use-after-free vulnerabilities. The below patches are fully independent and can be cherry-picked separately. Since we convert all kernel subsystems in the same fashion, resulting in about 300 patches, we have to group them for sending at least in some fashion to be manageable. Please excuse the long cc list.
