[mm-unstable,0/8] convert hugepage memory failure functions to folios

Message

============== OVERVIEW ===========================
This series contains a 1:1 straightforward page to folio conversion for
memory failure functions which deal with huge pages. I renamed a few
functions to fit with how other folio operating functions are named.
These include:

hugetlb_clear_page_hwpoison -> folio_clear_hugetlb_hwpoison
free_raw_hwp_pages -> folio_free_raw_hwp
__free_raw_hwp_pages -> __folio_free_raw_hwp
hugetlb_set_page_hwpoison -> folio_set_hugetlb_hwpoison

The goal of this series was to reduce users of the hugetlb specific
page flag macros which take in a page so users are protected by
the compiler to make sure they are operating on a head page.

Sidhartha Kumar (8):
  mm/memory-failure: convert __get_huge_page_for_hwpoison() to folios
  mm/memory-failure: convert try_memory_failure_hugetlb() to folios
  mm/memory-failure: convert hugetlb_clear_page_hwpoison to folios
  mm/memory-failure: convert free_raw_hwp_pages() to folios
  mm/memory-failure: convert raw_hwp_list_head() to folios
  mm/memory-failure: convert __free_raw_hwp_pages() to folios
  mm/memory-failure: convert hugetlb_set_page_hwpoison() to folios
  mm/memory-failure: convert unpoison_memory() to folios

Hi Sidhartha,

I looked through the patchset and all look fine to me.  And I tested the
patchset with v6.2-rc3 and no new issue is detected (I failed to boot with
latest mm-unstable, but maybe that should not be caused by your patches).

Thank you very much,

for the whole series.

Thanks for your review and testing.

It looks like the boot failure has been described here: 
https://lore.kernel.org/linux-mm/[e-mail]/T/#u 
and is not caused by this patch series.

Thanks,
