From 20359f27e8ff115f7cddf3da5b3a6cdcca2e650d Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 24 May 2011 10:23:22 +0200 Subject: cfq-iosched: remove unused 'group_changed' in cfq_service_tree_add() The 'group_changed' variable is initialized to 0 and never changed, so checking the variable is meaningless. It is a leftover from 0bbfeb832042 ("cfq-iosched: Always provide group iosolation."). Let's get rid of it.
