| |
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.
