Re: [PATCH 0/2] mm: avoid redundant reads of the vm_refcnt cacheline in anonymous faults

[Lorenzo Stoakes (ARM)]

Thanks for the report.

You are a complete newcomer to mm, and you are sending very subtle changes
to a core part of it, so I am not confident that you have the depth of
understanding the kernel requires for such work. See
https://docs.kernel.org/process/generated-content.html

I'll therefore take over this change and treat this as a bug report.

I will give you due credit for reporting the issue of course.

I'd like to collaborate on the perf measurements however, so if you could
re-run your test results on my series when I send it that'd be appreciated.

In general it seems that the actual issue is the debug assertion, given you
state only vma_has_anon_rmap() as a problem here.

In general in future - while we're fine with you using LLMs, newcomers
should work on small, incremental changes to mm to build up understanding
first.
