I have updated the QEMU 9P setup wiki page about this 'msize' issue. For
some reason the dedicated anchor 'msize' does not work though:

https://wiki.qemu.org/Documentation/9psetup#msize

Not sure whether that's a wiki installation problem? When I view the wiki
source, it looks like it is showing some errors there.

v1->v2:

  * Updated commit log message to make it more clear why the client cannot
    auto pick a good value for 'msize'.

  * Added a web link to the log message, pointing to the appropriate QEMU
    wiki page which explains the 'msize' issue in detail.

Message-ID of previous version (v1):
  E1kDR8W-0001s4-Sr@lizzy.crudebyte.com

AFAICT the wiki derives the anchor from the section name, ie.

https://wiki.qemu.org/Documentation/9psetup#Performance_Considerations

It's a bit longer than #msize but it works. I don't know if you can
add anchors manually in the wiki.

It seems you could achieve this without the template:

== <span id="msize">Performance Considerations</span> ==

What I tried was this (as wiki source):

<!-- NOTE: anchor 'msize' is linked by a QEMU 9pfs log message in 9p.c  -->
{{anchor|msize}}
== Performance Considerations ==

Which "should" work according to:
https://en.wikipedia.org/wiki/Template:Anchor

However after I did those changes I saw some template errors as comment in the 
generated HTML sources, which now are gone at least.

I wait a bit to see if it is maybe just a caching problem. If it still doesn't 
work in a while, I will update it with your solution a bit later.

Thanks for the hint!

Best regards,
