that was never used.

Below is a patch that cleans up some of this, supposedly without
changing any behaviour:
* Whitespace cleanups
* Introduce DBG()
* BUG_ON() instead of if () { BUG(); }
* Remove some of the deep nesting to make the code flow more
comprehensible
* Some mask operations were simplified

When a semantic match occurs either success, not found or an error
(for matching unreachable routes/blackholes) is returned. fib_trie
ignores the errors and looks for a different matching route. Treat
results other than "no match" as success and end lookup.

Below a patch to preallocate memory when doing resize of trie (inflate halve)
If preallocations fails it just skips the resize of this tnode for this time.
The oops we got when killing bgpd (with full routing) is now gone.
Patrick memory patch is also used.

Inflating a node a couple of times makes it exceed the 128k kmalloc limit.
Use __get_free_pages for allocations > PAGE_SIZE, as in fib_hash.

This should help up the insertion... but the resize is more crucial.
and complex and needs some thinking.
