# \[PATCH 2/4\] tools/virtio: Add missing spin\_lock\_init on virtio\_test - From: Cristian Marussi \ - Date: 2022-02-08 15:41:11 - List: linux-arm-kernel - Page: https://ratatoskr.run/linux-arm-kernel/2022/02/1662973 - Thread: https://ratatoskr.run/linux-arm-kernel/2022/02/1662937/t.md ```text A missing spin_lock_init() call can cause the test to hang indefinitely on spin_lock() at virtqueue creation time.
