Yeah, thanks for figuring this out.

I'll simply rebase your previous patch on the tip:x86/platform branch
since it is documentation stuff only and there's only one patch ontop
which updates MAINTAINERS but I don't think it'll be the end of the
world if those two got rebased.

Thx.

After scratching my head for a while, I found that the issue was missing empty 
lines before three different code-block sections.
The line number is definitely bogus, but I wasn't able to discover why.

You can find my patch at: https://lkml.org/lkml/2020/11/30/1196
The patch depends on the v2 patch set Mike Travis  
submitted, which hasn't made it to tip yet.

Yah, I can reproduce but I have no clue what sphinx wants from me. Line
2 looks ok which could mean that the warning line it points to is bogus.

Justin, this is all yours. :)

linux-next: build warnings after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (htmldocs) produced
these warnings:

indentation.
Documentation/ABI/testing/sysfs-firmware-sgi_uv:2: WARNING: Unexpected 
indentation.

Actually TCP and DCCP jprobes usages are similar to that SCTP usage 
(maybe derived from TCP one). For those usages, we can not replace
it with kprobe/ftrace because it depends on the arguments of target funcs.
For such use-cases, we have 3 options;
 - Remove entirely feature if possible (like no more used).
 - Replace it with trace-events, and handle the event from kernel as sched 
tracer does.
 - Just introduce trace-events, remove usage, and trace it via ftrace or perf.

At a glance, all network probes are just used for printing out the event,
so we can just introduce trace-events and remove usage. I will try it.

Thank you,

Ideal would be to just fix all these places: convert code where the facility 
appears to be actively used, remove code where it looks unused. If maintainers 
don't reply, I can apply them to a separate branch in -tip.

For example I'm pretty sure we can just remove the jprobes usage in SCTP.

I saw some discussion of this, so I assume ti will be fixed soon.
