Subject[PATCH 0/2] Better support for THP in page cache
Date
This is the first step towards representing THPs more efficiently in
the page cache. The next step is to insert one head page instead of
HPAGE_PMD_NR. This passes a Trinity run, but I'm sure there's a
better test-case out there for THP.

Matthew Wilcox (2):
mm: Remove redundant test from find_get_pages_contig
page cache: Store only head pages in i_pages

include/linux/pagemap.h | 9 ++++
mm/filemap.c | 106 +++++++++++-----------------------------
mm/khugepaged.c | 4 +-
mm/shmem.c | 2 +-
mm/swap_state.c | 2 +-
