From 2840537228fba95e05cab1a6b5719c61982db279 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 6 Oct 2009 15:33:29 -0600 Subject: vsprintf: fix io/mem resource width The leading "0x" consumes field width, so leave space for it in addition to the 4 or 8 hex digits. This means we'll print "0x0000-0x01df" rather than "0x00-0x1df", for example.
