This series, for dm and bcache parts, replaces atomic_t reference
counters with the new refcount_t type and API (see include/linux/refcount.h).
By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.
The patches are fully independent and can be cherry-picked separately.
Patches are based on top of linux-next as of yesterday.
If there are no objections to the patches, please merge them via respective trees
Elena Reshetova (4):
bcache: convert cached_dev.count from atomic_t to refcount_t
dm cache: convert dm_cache_metadata.ref_count from atomic_t to
refcount_t
dm: convert dm_dev_internal.count from atomic_t to refcount_t
dm: convert table_device.count from atomic_t to refcount_t
