Pretty please, can we do it in the core code, not in thermal/? There are other reasons kernel may want to shut the system down, like for example critical battery, and if both thermal _and_ bad battery happen, we want just one shutdown... > Reported-by: Keerthy <j-keerthy@xxxxxx> > Signed-off-by: Keerthy <j-keerthy@xxxxxx> And here probably we need your full name.
