[PATCH 00/17] Refactor generic_file_buffered_read

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

This is a combination of Christoph's work to refactor
generic_file_buffered_read() and my THP support on top of Kent's patches
which are currently in -mm.  I really like where this ended up.

Christoph Hellwig (2):
  mm/filemap: rename generic_file_buffered_read to filemap_read
  mm: simplify generic_file_read_iter

Matthew Wilcox (Oracle) (15):
  mm/filemap: Rename generic_file_buffered_read subfunctions
  mm/filemap: Use THPs in generic_file_buffered_read
  mm/filemap: Pass a sleep state to put_and_wait_on_page_locked
  mm/filemap: Support readpage splitting a page
  mm/filemap: Inline __wait_on_page_locked_async into caller
  mm/filemap: Don't call ->readpage if IOCB_WAITQ is set
  mm/filemap: Change filemap_read_page calling conventions
  mm/filemap: Change filemap_create_page arguments
  mm/filemap: Convert filemap_update_page to return an errno
  mm/filemap: Move the iocb checks into filemap_update_page
  mm/filemap: Add filemap_range_uptodate
  mm/filemap: Split filemap_readahead out of filemap_get_pages
  mm/filemap: Remove parameters from filemap_update_page()
  mm/filemap: Restructure filemap_get_pages
  mm/filemap: Don't relock the page after calling readpage
