From: Quentin Perret
Date: Wed Jun 02 2021 - 05:43:56 EST


Hi all,

This is a v2 of the patch series previously posted here:

https://lore.kernel.org/r/20210527125134.2116404-1-qperret@xxxxxxxxxx/

Please refer to the cover letter of v1 for the context and motivation
behind the series.

Changes since v1:
- Added comment/doc in page_alloc.c explaining the locking expectations;
- Removed unnecessary casts in the 'page-to-list-node' helpers;
- A few other cosmetic changes in the allocator.

Thanks,
Quentin
