I'm confused. That wasn't a patch submission, but reporting performance
results for my patch from late 2024? (and thanks for those!)
The patch was also already merged in late 2024:
commit d4148aeab412432bf928f311eca8a2ba52bb05df
Author: Vlastimil Babka <vbabka@suse.cz>
Date: Thu Oct 24 17:12:29 2024 +0200
mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes
So there's nothing more to do here AFAIK.
