Resending. The original post is [1].

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[2].

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.

[1] v2: https://lore.kernel.org/r/20201210160038.31441-1-pmladek@suse.com
[2] v1: https://lore.kernel.org/r/20191024114928.15377-1-pmladek@suse.com

Petr Mladek (7):
  watchdog: Rename __touch_watchdog() to a better descriptive name
  watchdog: Explicitly update timestamp when reporting softlockup
  watchdog/softlockup: Report the overall time of softlockups
  watchdog/softlockup: Remove logic that tried to prevent repeated
    reports
  watchdog: Fix barriers when printing backtraces from all CPUs
  watchdog: Cleanup handling of false positives
  Test softlockup
