[PATCH v2 0/7] watchdog/softlockup: Report overall time and some cleanup
From: Petr Mladek
Date: Thu Dec 10 2020 - 11:41:24 EST
I dug deep into the softlockup watchdog history when time permitted
this year. And reworked the patchset that fixed timestamps and
cleaned up the code[1].
I split it into very small steps and did even more code clean up.
The result looks quite strightforward and I am pretty confident
with the changes.
