Note: our previous thread didn't finish in any conclusion, so I am resending this now (rebased at latest linux-next) to revive the discussion. refcount_t is slowly becoming a standard for refcounters and we would really like to make all conversions done where it is applicable. ****** This series, for xfs, 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 lead 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.
