hung_task: decrement sysctl_hung_task_warnings only if it is positive
Since sysctl_hung_task_warnings == -1 is allowed (infinite warnings), commit 48a6d64e ("hung_task: allow hung_task_panic when hung_task_warnings is 0") should decrement it only when it is not -1. This prevents the kernel from ceasing warnings after the first 4294967295 ;) Signed-off-by:Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Cc: John Siddle <jsiddle@redhat.com> Signed-off-by:
