From d4339569a6f8bb1e703337175dcd4fd4bcd5d891 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 17 Jul 2013 19:49:41 +0200 Subject: [PATCH] perf session: Use session->fd instead of passing fd as argument Using session->fd instead of passing fd as argument because it's always session->fd that's passed as fd argument.
