Hi Andrew,

I wanted to make a v2 of this series to replace 10 with min(32, nrcpus - 1)
(see computation of nr_parallel in uffd-stress.c) but I see that it has
been pulled into mm-new, and on top of that, the following patch makes
things complicated to just revert my commits in mm-new and make v2 on top of that -
https://lore.kernel.org/all/20250830033424.8C44FC4CEF0@smtp.kernel.org/

So shall I just send a new separate patch based off mm-new?
