Subject: [PATCH 00/11] Remove assumptions of THP size
Date: Tue, 8 Sep 2020 20:55:27 +0100 [thread overview]
Message-ID: <20200908195539.25896-1-willy@infradead.org> (raw)
There are a number of places in the VM which assume that a THP is a PMD
in size. That's true today, and remains true after this patch series,
but this is a prerequisite for switching to arbitrary-sized THPs.
thp_nr_pages() still returns either HPAGE_PMD_NR or 1, but will be
changed later.
Kirill A. Shutemov (2):
mm/huge_memory: Fix total_mapcount assumption of page size
mm/huge_memory: Fix split assumption of page size
Matthew Wilcox (Oracle) (9):
mm/filemap: Fix page cache removal for arbitrary sized THPs
mm/memory: Remove page fault assumption of compound page size
mm/page_owner: Change split_page_owner to take a count
mm/huge_memory: Fix page_trans_huge_mapcount assumption of THP size
mm/huge_memory: Fix can_split_huge_page assumption of THP size
mm/rmap: Fix assumptions of THP size
mm/truncate: Fix truncation for pages of arbitrary size
mm/page-writeback: Support tail pages in wait_for_stable_page
mm/vmscan: Allow arbitrary sized pages to be paged out
