pkt_sched: sch_htb: Fix deadlock in hrtimers triggered by HTB
[ Upstream commit: none
This is a quick fix for -stable purposes. Upstream fixes these
problems via a large set of invasive hrtimer changes. ]
Most probably there is a (still unproven) race in hrtimers (before
2.6.29 kernels), which causes a corruption of hrtimers rbtree. This
patch doesn't fix it, but should let HTB avoid triggering the bug.
