I didn't see the patchset shown on:
https://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm.git/log/?h=mm-unstable
yet. I believe the patchset will be in mm-unstable soon.
From the cover letter:
The point of all this is better performance, and Fengwei Yin has
measured improvement on x86. I suspect you'll see improvement on
your architecture too. Try the new will-it-scale test mentioned here:
https://lore.kernel.org/linux-mm/20230206140639.538867-5-fengwei.yin@intel.com/
You'll need to run it on an XFS filesystem and have
CONFIG_TRANSPARENT_HUGEPAGE set.
It's for performance testing. For functionality, I used:
- System boot/reboot.
- Using browser to access internet, Thunderbird to check email.
- Build kernel.
Regards
Yin, Fengwei
