From 8b414521bc5375ae8ba18c083af95d44b8da0d04 Mon Sep 17 00:00:00 2001 From: Marcelo Tosatti Date: Fri, 11 Oct 2013 21:39:26 -0300 Subject: hung_task: add method to reset detector In certain occasions it is possible for a hung task detector positive to be false: continuation from a paused VM, for example. Add a method to reset detection, similar as is done with other kernel watchdogs.
