Two minor conflicts:
1) net/ipv4/route.c, adding a new local variable while
moving another local variable and removing it's
initial assignment.
2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes.
One pretty prints the port mode differently, whilst another
changes the driver to try and obtain the port mode from
the port node rather than the switch node.

Remove link to litmus tests that didn't make it to upstream. Fix ringbuf
benchmark link.
I wasn't able to test this with `make htmldocs`, unfortunately, because of
Sphinx dependencies. But bench_ringbufs.c path is certainly correct now.

Pull documentation updates from Jonathan Corbet:
"It's been a busy cycle for documentation - hopefully the busiest for a
while to come. Changes include:
- Some new Chinese translations
- Progress on the battle against double words words and non-HTTPS
URLs
- Some block-mq documentation
- More RST conversions from Mauro. At this point, that task is
essentially complete, so we shouldn't see this kind of churn again
for a while. Unless we decide to switch to asciidoc or
something...:)
- Lots of typo fixes, warning fixes, and more"

It's a follow-up for discussion in [1].
drgn tool bpf_inspect.py was merged to drgn repo in [2]. Document it
in kernel tree to make BPF developers aware that the tool exists and
can help with getting BPF state unavailable via UAPI.
For now it's just one tool but the doc is written in a way that allows
to cover more tools in the future if needed.
Please refer to the doc itself for more details.
The patch was tested by `make htmldocs` and sanity-checking that
resulting html looks good.
v2 -> v3:
- two sections: "Description" and "Getting started" (Daniel);
- add examples in "Getting started" section (Daniel);
- add "Customization" section to show how tool can be customized.
v1 -> v2:
- better "BPF drgn tools" section (Alexei)

Always use init_net flow dissector BPF program if it's attached and fall
back to the per-net namespace one. Also, deny installing new programs if
there is already one attached to the root namespace.
Users can still detach their BPF programs, but can't attach any
new ones (-EEXIST).
