Martin KaFai Lau says: ==================== bpf: Support bpf rbtree traversal and list peeking From: Martin KaFai Lau <martin.lau@kernel.org> The RFC v1 [1] showed a fq qdisc implementation in bpf that is much closer to the kernel sch_fq.c. The fq example and bpf qdisc changes are separated out from this set. This set is to focus on the kfunc and verifier changes that enable the bpf rbtree traversal and list peeking. v2: - Added tests to check that the return value of the bpf_rbtree_{root,left,right} and bpf_list_{front,back} is marked as a non_own_ref node pointer. (Kumar) - Added tests to ensure that the bpf_rbtree_{root,left,right} and bpf_list_{front,back} must be called after holding the spinlock. - Squashed the selftests adjustment to the corresponding verifier changes to avoid bisect failure. (Kumar) - Separated the bpf qdisc specific changes and fq selftest example from this set.

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 reStructuredText 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.
