Subject: [PATCH 05/20] tools lib traceevent: Fix trace_printk for long integers
Date: Thu, 5 Jul 2012 12:45:03 -0300 [thread overview]
Message-ID: <1341503118-13198-6-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1341503118-13198-1-git-send-email-acme@infradead.org>
From: Wolfgang Mauerer <wolfgang.mauerer@siemens.com>
On 32 bit systems, a conversion of the trace_printk format string
"%lu" -> "%llu" is intended (similar for %lx etc.) when a trace was
taken on a machine with 64 bit long integers. However, the current
code computes the bogus transformation "%lu" -> "%u". Fix this.
Besides that, the transformation is only required on systems that don't
use 64 bits for long integers natively.
