As promised earlier [1], here are the patches which I would like to
merge into 5.11 to support THPs.  They depend on that earlier series.
If there's anything in here that you'd like to see pulled out and added
to that earlier series, let me know.

There are a couple of pieces in here which aren't exactly part of
iomap, but I think make sense to take through the iomap tree.

Matthew Wilcox (Oracle) (11):
  fs: Make page_mkwrite_check_truncate thp-aware
  mm: Support THPs in zero_user_segments
  mm: Zero the head page, not the tail page
  block: Add bio_for_each_thp_segment_all
  iomap: Support THPs in iomap_adjust_read_range
  iomap: Support THPs in invalidatepage
  iomap: Support THPs in read paths
  iomap: Change iomap_write_begin calling convention
  iomap: Support THPs in write paths
  iomap: Inline data shouldn't see THPs
  iomap: Handle tail pages in iomap_page_mkwrite
