The hash types do not acquire set->lock, they use 'region locking' where
only part of the hash table is locked. Parallel inserts and deletes are
possible and CPUs can race on ->ext_size update. Switch to atomic64_t.
This leaves another bug unresolved: there still can be a race on
comment extension re-init. This will be handled in a later commit
when converting to rhashtable backend.
Fixes:
