[PATCH 0/3] Use nth_page() in place of direct struct page manipulation

[Zi Yan]

From: Zi Yan <ziy@xxxxxxxxxx>

On SPARSEMEM without VMEMMAP, struct page is not guaranteed to be
contiguous, since each memory section's memmap might be allocated
independently. hugetlb pages can go beyond a memory section size, thus
direct struct page manipulation on hugetlb pages/subpages might give
wrong struct page. Kernel provides nth_page() to do the manipulation
properly. Use that whenever code can see hugetlb pages.

The patches are on top of next-20230830.

Zi Yan (3):
  mm: use nth_page() in place of direct struct page manipulation.
  fs: use nth_page() in place of direct struct page manipulation.
  mips: use nth_page() in place of direct struct page manipulation.
