Issue of the Implementation # L0264
Brief
z3fold: spinlock left locked in page reclaim
Detailed Description
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 }
There should be spin_unlock(&pool->lock); just before return.
