From 8afe3d7d64eaae67e96ea48af2d98df1e15cfc65 Mon Sep 17 00:00:00 2001 From: "Alan D. Brunelle" Date: Tue, 19 Dec 2006 08:18:38 +0100 Subject: PATCH: blkparse: fix probem with empty trace files stopping the check for other files Fix problem where empty input files cause premature parsing of files. Had a problem where CPU 0 opened a file with 0 traces, and that caused the run to end before processing other trace files.
