- An architecture selects this when it has implemented refcount_t
- using open coded assembly primitives that provide an optimized
- refcount_t implementation, possibly at the expense of some full
- refcount state checks of CONFIG_REFCOUNT_FULL=y.
-
- The refcount overflow check behavior, however, must be retained.
- Catching overflows is the primary security concern for protecting
- against bugs in reference counts.

-config REFCOUNT_FULL
- bool "Perform full reference count validation at the expense of speed"
- help
- Enabling this switches the refcounting infrastructure from a fast
- unchecked atomic_t implementation to a fully state checked
- implementation, which can be (slightly) slower but provides protections
- against various use-after-free conditions that can be used in
- security flaw exploits.
