From 0bc6484d58bd7f43fbf6fc87c7974910b698489c Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Tue, 4 Oct 2016 14:35:58 +0100 Subject: trace: pass trace-events to tracetool as a positional param MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of reading the contents of 'trace-events' from stdin, accept the filename as a positional parameter. This also allows for reading from multiple files, though this facility is not used at this time. Reviewed-by: Stefan Hajnoczi Reviewed-by: Lluís Vilanova Signed-off-by: Daniel P.
