====================
Netfilter fixes for net

1) Fix overlap detection in rbtree set backend: Detect overlap by going
   through the ordered list of valid tree nodes. To shorten the number of
   visited nodes in the list, this algorithm descends the tree to search
   for an existing element greater than the key value to insert that is
   greater than the new element.

2) Fix for the rbtree set garbage collector: Skip inactive and busy
   elements when checking for expired elements to avoid interference
   with an ongoing transaction from control plane.

This is a rather large fix coming at this stage of the 6.2-rc. Since
33c7aba0b4ff ("netfilter: nf_tables: do not set up extensions for end
interval"), bogus overlap errors in the rbtree set occur more frequently.
