[alsa-devel] [PATCH 0/9] tools subsystem refcounter conversions

[Elena Reshetova]

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.

Elena Reshetova (9):
  tools: convert cgroup_sel.refcnt from atomic_t to refcount_t
  tools: convert cpu_map.refcnt from atomic_t to refcount_t
  tools: convert comm_str.refcnt from atomic_t to refcount_t
  tools: convert dso.refcnt from atomic_t to refcount_t
  tools: convert map.refcnt from atomic_t to refcount_t
  tools: convert map_groups.refcnt from atomic_t to refcount_t
  tools: convert perf_map.refcnt from atomic_t to refcount_t
  tools: convert thread.refcnt from atomic_t to refcount_t
  tools: convert thread_map.refcnt from atomic_t to refcount_t
