From 1f23f12151ab508728dd5fca12180e2fce6c6949 Mon Sep 17 00:00:00 2001 From: Vivek Goyal Date: Wed, 3 Oct 2012 16:57:00 -0400 Subject: [PATCH] cfq-iosched: Get rid of unnecessary local variable Use of local varibale "n" seems to be unnecessary. Remove it. This brings it inline with function __cfq_group_st_add(), which is also doing the similar operation of adding a group to a rb tree. No functionality change here.
