[patch v2 04/10] kdump: Trigger kdump via panic notifier chain on s390

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Michael Holzheu <holzheu@xxxxxxxxxxxxxxxxxx>

On s390 we have the possibility to configure actions that are executed in
case of a kernel panic. E.g. it is possible to automatically trigger an s390
stand-alone dump. The actions are called via a panic notifier.  We also want
to trigger kdump via the notifier call chain. Therefore this patch disables
for s390 the direct kdump invocation in the panic() function.
