From: Johannes Weiner Date: Tue, 6 Jan 2009 22:40:32 +0000 (-0800) Subject: bootmem: print request details before BUG_ON(them) X-Git-Tag: v2.6.29-rc1~394 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=594fe1a044325bb0a1a49ca7d086e3df4f1df59a;p=linux-2.6-omap-h63xx.git 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.
