Subject: Re: [PATCH v7 00/31] mm/virtio: skip redundant zeroing of host-zeroed pages
Date: Wed, 13 May 2026 09:36:06 +0200	[thread overview]
Message-ID: <e7e9b30f-ee5c-44c4-b377-d70156be41e9@kernel.org> (raw)
In-Reply-To: <cover.1778616612.git.mst@redhat.com>

> Changes since v6 (address review by Gregory Price):
> - Rework hugetlb: use gfp_t parameter instead of bool zero /
>   bool *zeroed.  Sink zeroing inside alloc_hugetlb_folio().
>   Pass raw fault address (user_addr) for cache-friendly zeroing
>   on both pool-page and fresh allocation
>   paths.  (Suggested by Gregory Price)
> - Reorder compaction_alloc_noprof() to call prep_compound_page
>   before post_alloc_hook for consistency.
>   (Suggested by Gregory Price)
> - Reorder: interleave fix first, PageReported propagation and
>   capacity fix moved to front as dependencies.
> - Add USER_ADDR_NONE comments in mmap.c and internal.h explaining why -1 is
>   never a valid userspace address.
> - Fix err uninitialized warning in virtballoon_free_page_report().
> - Lots of commit log tweaks.
> 
> Also in v7:
> - Fix hugetlb pool page zeroing to use vmf->real_address
>   (the actual faulting subpage) instead of vmf->address
>   (hugepage-aligned), preserving cache-friendly zeroing
>   locality that upstream had at the callsite.
> - Remove dead/broken alloc_hugetlb_folio !CONFIG_HUGETLB_PAGE
>   stub (returned NULL but callers check IS_ERR).

Please wait at least a week before sending out new versions of this size.

It's just a lot of noise in people's inbox, and as raised, a lot of people won't
manage to review this before next month.
