[PATCH 3/6] bdi: Use refcount_t for reference counting instead atomic_t

refcount_t type and corresponding API should be used instead of atomic_t when the variable is used as a reference counter. This allows to avoid accidental refcounter overflows that might lead to use-after-free situations. Cc: linux...@kvack.org Cc: Andrew Morton Suggested-by: Peter Zijlstra Acke
