From: "Kirill A. Shutemov" <kirill.shutemov@xxxxxxxxxxxxxxx>
My patchset which introduces transparent huge page cache is pretty big and
hardly reviewable. Dave Hansen suggested to split it in few parts.
This is the first part: preparation work. I think it's useful without rest
patches.
There's one fix for bug in lru_add_page_tail(). I doubt it's possible to
trigger it on current code, but nice to have it upstream anyway.
Rest is cleanups.
Patch 8 depends on patch 7. Other patches are independent and can be
applied separately.
Please, consider applying.
Kirill A. Shutemov (8):
mm: drop actor argument of do_generic_file_read()
thp, mm: avoid PageUnevictable on active/inactive lru lists
thp: account anon transparent huge pages into NR_ANON_PAGES
mm: cleanup add_to_page_cache_locked()
thp, mm: locking tail page is a bug
thp: move maybe_pmd_mkwrite() out of mk_huge_pmd()
thp: do_huge_pmd_anonymous_page() cleanup
thp: consolidate code between handle_mm_fault() and
do_huge_pmd_anonymous_page()
