====================
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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
