From 594fe1a044325bb0a1a49ca7d086e3df4f1df59a Mon Sep 17 00:00:00 2001 From: Johannes Weiner Date: Tue, 6 Jan 2009 14:40:32 -0800 Subject: bootmem: print request details before BUG_ON(them) Moving the request details print-out before the sanity checks that might panic() enables us to analyse invalid requests without having access to the line information of the stack dump.
