81771b3b20 [NET_SCHED]: Revert "HTB: fix incorrect use of RB_EMPTY_NODE"
With commit 10fd48f237 [1] ,  RB_EMPTY_NODE
changed behaviour so it returns true when the node is empty as expected.
Hence Patrick McHardy's fix for sched_htb.c should be reverted.

787e0617e5 [NET_SCHED]: HTB: fix incorrect use of RB_EMPTY_NODE
Fix incorrect use of RB_EMPTY_NODE in htb_safe_rb_erase, which makes it
skip nodes within the rbtree instead of nodes not in the tree, resulting
in crashes later on.

The root cause for this seems to be the very counter-intuitive behaviour
of the RB_EMPTY_NODE macro, which returns _false_ when the node is empty.

3696f625e2 [HTB]: rbtree cleanup
Add code to initialize rb tree nodes, and check for double deletion.
This is not a real fix, but I can make it trap sometimes and may
be a bandaid for: http://bugzilla.kernel.org/show_bug.cgi?id=6681

0cef296da9 [HTB]: Use hlist for hash lists.
Use hlist instead of list for the hash list. This saves
space, and we can check for double delete better.

b3a6251915 [PKT_SCHED] HTB: initialize upper bound properly
The upper bound for HTB time diff needs to be scaled to PSCHED
units rather than just assuming usecs.  The field mbuffer is used
in TDIFF_SAFE(), as an upper bound.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
