5.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Zijian Zhang <zijianzhang@xxxxxxxxxxxxx> [ Upstream commit 7d6d8f0c8b700c9493f2839abccb6d29028b4219 ] We find that when lock debugging is on, notifications may not come in order. Thus, we have order checking outputs managed by cfg_verbose, to avoid too many outputs in this case.
