Worker threads in D state since c5a94a618e7ac86 (workqueue: Use TASK_IDLE)
From: Markus Trippelsdorf
Date: Sun Sep 10 2017 - 03:37:09 EST
Since:
commit c5a94a618e7ac86b20f53d947f68d7cee6a4c6bc
Author: Peter Zijlstra <peterz@xxxxxxxxxxxxx>
Date: Wed Aug 23 13:58:44 2017 +0200
workqueue: Use TASK_IDLE
all worker threads are in D state. They all show up when using "magic
SysRq w". In htop they all have big fat red 'D' in the state column.
Is this really desirable?
I have attached the output of "ps aux" after boot and the SysRq-w
output.
