From 6beba7adbe092e63dfe8d09fbd1e3ec140474a13 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 21 Oct 2009 17:34:06 -0200 Subject: perf tools: Unify debug messages mechanisms We were using eprintf in some places, that looks at a global 'verbose' level, and at other places passing a 'v' parameter to specify the verbosity level, unify it by introducing pr_{err,warning,debug,etc}, just like in the kernel.
