From: Shaohua Li <shli@fb.com>

Basically this is a copy of commit 001e4a8775f6(ext4: implement cgroup
writeback support). Tested with a fio test, verified writeback is
throttled against cgroup io.max write bandwidth, also verified moving
the fio test to another cgroup and the writeback is throttled against
new cgroup setting.
