pkt_sched: Revert tasklet_hrtimer changes.
These are full of unresolved problems, mainly that conversions don't work 1-1 from hrtimers to tasklet_hrtimers because unlike hrtimers tasklets can't be killed from softirq context. And when a qdisc gets reset, that's exactly what we need to do here. We'll work this out in the net-next-2.6 tree and if warranted we'll backport that work to -stable. This reverts the following 3 changesets: a2cb6a4dd470d7a64255a10b843b0d188416b78f ("pkt_sched: Fix bogon in tasklet_hrtimer changes.") 38acce2d7983632100a9ff3fd20295f6e34074a8 ("pkt_sched: Convert CBQ to tasklet_hrtimer.") ee5f9757ea17759e1ce5503bdae2b07e48e32af9 ("pkt_sched: Convert qdisc_watchdog to tasklet_hrtimer") Signed-off-by: David S.
