From 04a418495e0852263d77c4fb82adf470feaafef3 Mon Sep 17 00:00:00 2001 From: Thomas Meyer Date: Sat, 28 Mar 2015 10:07:37 +0100 Subject: um: add a kmsg_dumper Add a kmsg_dumper, that dumps the kmsg buffer to stdout, when no console is available. This an enables the printing of early panic() calls triggered in uml_postsetup(). When a panic() call happens so early in the UML kernel no earlyprintk/console is available yet, but with a kmsg_dumper in place the kernel message buffer will be outputted to the user, to give a better hint, of what the failure was.
