         new->inode_pool = mem_pool_new (inode_t, lru_limit);

the above change will affect function in inode_table_prune:
                while (table->lru_limit
                       && table->lru_size > (table->lru_limit)) {

                        entry = list_entry (table->lru.next, inode_t, list);

                        table->lru_size--;
                        __inode_retire (entry);

                        ret++;
                }

it will lead to __inode_retire without notify the kernel, and while kerenl do
fuse_forget, it finally will lead to invalid memory access and finally lead to
coredump, isn't it?
