CONFIG_DEBUG_REFCOUNT: Verbose refcount checks

General informations

The Linux kernel configuration item CONFIG_DEBUG_REFCOUNT:

Help text

Say Y here if you want reference counters (refcount_t and kref) to generate WARNs on dubious usage. Without this refcount_t will still be a saturating counter and avoid Use-After-Free by turning it into a resource leak Denial-Of-Service.

Use of this option will increase kernel text size but will alert the admin of potential abuse.

If in doubt, say "N".
