Subject[RFC 00/15] Large pages in the page-cache
Date
From: "Matthew Wilcox (Oracle)" <willy@infradead.org>

Here's what I'm currently playing with. I'm having trouble _testing_
it, but since akpm's patches were just merged into Linus' tree, I
thought this would be a good point to send out my current work tree.
Thanks to kbuild bot for finding a bunch of build problems ;-)

Matthew Wilcox (Oracle) (12):
mm: Use vm_fault error code directly
fs: Introduce i_blocks_per_page
mm: Add file_offset_of_ helpers
iomap: Support large pages
xfs: Support large pages
xfs: Pass a page to xfs_finish_page_writeback
mm: Make prep_transhuge_page tail-callable
mm: Add __page_cache_alloc_order
mm: Allow large pages to be added to the page cache
mm: Allow find_get_page to be used for large pages
mm: Remove hpage_nr_pages
xfs: Use filemap_huge_fault

William Kucharski (3):
mm: Support removing arbitrary sized pages from mapping
mm: Add a huge page fault handler for files
mm: Align THP mappings for non-DAX
