From e2cddd104051ee3f47dddaa0b8d54a5193f0971b Mon Sep 17 00:00:00 2001 From: Syed Rameez Mustafa Date: Mon, 15 Jul 2013 11:52:09 -0700 Subject: kernel/lib: add additional debug capabilites for data corruption Data corruptions in the kernel often end up in system crashes that are easier to debug closer to the time of detection. Specifically, if we do not panic immediately after lock or list corruptions have been detected, the problem context is lost in the ensuing system mayhem. Add support for allowing system crash immediately after such corruptions are detected. The CONFIG option controls the enabling/disabling of the feature.
