blk-cgroup: Initialize ioc->cgroup_changed at ioc creation time
If we don't explicitly initialize it to zero, CFQ might think that cgroup of ioc has changed and it generates lots of unnecessary calls to call_for_each_cic(changed_cgroup). Fix it. cfq_get_io_context() cfq_ioc_set_cgroup() call_for_each_cic(ioc, changed_cgroup) Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
