[PATCH 0/7] Overhaul find_get_entries and pagevec_lookup_entries

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

This started out as part of the THP patchset, but it's turned into a
nice simplification in its own right.  Essentially we end up unifying
find_get_entries() and pagevec_lookup_entries() into one function that's
better than either, and we get rid of a lot of code in the callers as
a result.

I'm running this through xfstests right now, but something similar to
this has already passed xfstests as part of the THP patchset.

I've done my best to avoid off-by-one errors for 'end', but I wouldn't be
surprised if I made a mistake.  We're not consistent with whether 'end'
is inclusive or exclusive and I didn't want to make extensive changes
to ensure they were consistent.

Matthew Wilcox (Oracle) (7):
  mm: Use pagevec_lookup in shmem_unlock_mapping
  mm: Rewrite shmem_seek_hole_data
  mm: Add an 'end' parameter to find_get_entries
  mm: Add an 'end' parameter to pagevec_lookup_entries
  mm: Remove nr_entries parameter from pagevec_lookup_entries
  mm: Pass pvec directly to find_get_entries
  mm: Remove pagevec_lookup_entries
