Hello!
z3fold_reclaim_page() contains the only return that may leave the function with pool->lock spinlock held.
669 spin_lock(&pool->lock); 670 if (kref_put(&zhdr->refcount, release_z3fold_page)) { 671 atomic64_dec(&pool->pages_nr); 672 return 0; 673 }
May be we need spin_unlock(&pool->lock); just before return?
