I have merged all the workqueue changes from Link: https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git/log/kernel/workqueue.c?h=v5.10-rt
And this problem can still reproduce.
I checked the patch from master tree too, it seems there is no existed patch can fix this problem.
Or are there any scheduler, process management related patches that might fix this problem?
