Subject: [PATCH 0/4] Use folio APIs in procfs
Date: Wed, 3 Apr 2024 18:14:51 +0100 [thread overview]
Message-ID: <20240403171456.1445117-1-willy@infradead.org> (raw)
Not sure whether Andrew or Christian will want to take this set of
fixes. We're down to very few users of the PageFoo macros, with proc
being a major user. After this patchset and another patchset I have
for khugepaged, we can get rid of PageActive, PageReadahead and
PageSwapBacked.
This patchset has the usual advantages in its own right of removing
hidden calls to compound_head(). We have the page table lock, so
the mapcount & refcount are stable and there can't be any races with
folios suddenly becoming tail pages.
Matthew Wilcox (Oracle) (4):
proc: Convert gather_stats to use a folio
proc: Convert smaps_page_accumulate to use a folio
proc: Pass a folio to smaps_page_accumulate()
proc: Convert smaps_pmd_entry to use a folio
