| |
This series, for nfs components, 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. If there are no objections to the patches, please merge them via respective trees.
Rebased on top of linux-next.
