in conf->r1bio_pool.wait.head pointing\nto a stack address.\nAccessing this address later can lead to a kernel panic.\n\nExample access path:\n\nraid1_reshape()\n{\n\t// newpool is on the stack\n\tmempool_t newpool, oldpool;\n\t// initialize newpool.wait.head to stack address\n\tmempool_init(&newpool, ...);\n\tconf->r1bio_pool = newpool;\n}\n\nraid1_read_request() or
