Subject[PATCH v2 0/9] watchdog: parameters to control hard and soft lockup detector individually
Date
This post follows up to https://lkml.org/lkml/2014/8/11/329.
During the discussion of that patch, Ingo Molnar commented in
https://lkml.org/lkml/2014/8/18/577.

"The softlockup and hardlockup detection control variables
should be in separate flags, inside and outside the kernel -
they (should) not relate to each other."

Please refer to [PATCH v2 7/9] for a description of the proposed
changes of the 'user interface' in /proc/sys/kernel and kernel
command line parameters.

There are no functional changes between the initial version in
https://lkml.org/lkml/2014/10/13/313 and v2. The new version is
merely a re-base to the following upstream commits.
