From 727ebd544f85285a223ecc6a2a57ef90202cdc7b Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 28 Nov 2013 11:30:14 +0100 Subject: perf tools: Use correct return type for readn function Changing readn function return type to ssize_t because read returns ssize_t not int. Changing callers holding variable types as well.
