[patch 0/3] net: Sanitizing hrtimer usage in net/sched/sch_cbq.c

While looking at the "Soft-Lockup/Race in networking in 2.6.31-rc1+195
( possibly caused by netem)" issue (http://lkml.org/lkml/2009/7/2/519)
I noticed some serious problems in the hrtimer related code of
net/sched/sched/sch_cbq.c.

The following patch series addresses these.

I'm not entirely sure whether patch [1/3] covers all possible
concurrent modifications, but it fixes the most obvious ones. The
remaining details are left to the networking experts.

Patches [1/3] and [2/3] might be stable material as well.

Thanks,

tglx
