Subject: [PATCH 00/22] Get rid of first tail page fields
Date: Sat, 31 Dec 2022 21:45:48 +0000 [thread overview]
Message-ID: <20221231214610.2800682-1-willy@infradead.org> (raw)
Continue the shrinkage of the struct page definition by getting rid of the
'first tail page' fields. I originally did this patch set before Hugh's
rewrite of the subpages_mapcount, so it needed substantial updates;
hope I didn't miss anything.
I hope you like the new names for compound_mapcount and
subpages_mapcount.
Matthew Wilcox (Oracle) (22):
mm: Remove folio_pincount_ptr() and head_compound_pincount()
mm: Convert head_subpages_mapcount() into folio_nr_pages_mapped()
doc: Clarify refcount section by referring to folios & pages
mm: Convert total_compound_mapcount() to folio_total_mapcount()
mm: Convert page_remove_rmap() to use a folio internally
mm: Convert page_add_anon_rmap() to use a folio internally
mm: Convert page_add_file_rmap() to use a folio internally
mm: Add folio_add_new_anon_rmap()
page_alloc: Use folio fields directly
