+++ This bug was initially created as a clone of Bug #1242377 +++

Description of problem:
-----------------------
There are few instances of 'gf_log' as seen under performance_xlators directory in the code base

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
RHGS 3.1 ( glusterfs-3.7.1-8.el6rhs )

Expected results:
-----------------
All gf_log instances should be ported to new logging framework
