[PATCH 0/4] fs, afs subsystem refcounter conversions

[Elena Reshetova <elena.reshetova@intel.com>]

Now when new refcount_t type and API are finally merged
(see include/linux/refcount.h), the following
patches convert various refcounters in the fs, afs 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 (4):
  fs, afs: convert afs_cell.usage from atomic_t to refcount_t
  fs, afs: convert afs_vlocation.usage from atomic_t to refcount_t
  fs, afs: convert afs_server.usage from atomic_t to refcount_t
  fs, afs: convert afs_volume.usage from atomic_t to refcount_t
