From 545b1214b36588ef7a1f334225bdf2b0134147ae Mon Sep 17 00:00:00 2001 From: Xiongfeng Wang Date: Sat, 20 Feb 2021 11:00:57 +0800 Subject: [PATCH] lockup_detector: init lockup detector after all the init_calls commit bef7d8e1432400f3d78339ac269167e09c15dabd openeuler. We call 'sdei_init' as 'subsys_initcall_sync'. lockup detector need to be initialised after sdei_init. The influence of this patch is that we can not detect the hard lockup in init_calls.
