This patchset includes all the filesystem and iomap changes needed to
support transparent huge pages.  A separate patchset will enable the MM
side of things.  I'm hoping Darrick agrees to take the first two patches
through the iomap tree,

These patches are for review.  They don't currently apply to the iomap
tree due to some conflicting patches.  I'll rebase on top of -rc1 once
it's out (they do apply to 5.9).  

Matthew Wilcox (Oracle) (14):
  fs: Support THPs in vfs_dedupe_file_range
  fs: Make page_mkwrite_check_truncate thp-aware
  iomap: Support THPs in BIO completion path
  iomap: Support THPs in iomap_adjust_read_range
  iomap: Support THPs in invalidatepage
  iomap: Support THPs in iomap_is_partially_uptodate
  iomap: Support THPs in readpage
  iomap: Support THPs in readahead
  iomap: Change iomap_write_begin calling convention
  iomap: Handle THPs when writing to pages
  iomap: Support THP writeback
  iomap: Inline data shouldn't see THPs
  iomap: Handle tail pages in iomap_page_mkwrite
  xfs: Support THPs
