From: Steven Rostedt Date: Wed, 3 Dec 2008 16:04:50 +0000 (-0500) Subject: trace: fix output of stack trace X-Git-Tag: v2.6.29-rc1~586^2~34^2~1 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=0a37119d963e876ca86912497346ec50dea2541b;p=linux-2.6-omap-h63xx.git trace: fix output of stack trace Impact: fix to output of stack trace If a function is not found in the stack of the stack tracer, the number printed is quite strange. This fixes the algorithm to handle missing functions better.
