[v2,0/9] THP iomap patches for 5.10

Message

These patches are carefully plucked from the THP series.  I would like
them to hit 5.10 to make the THP patchset merge easier.  Some of these
are just generic improvements that make sense on their own terms, but
the overall intent is to support THPs in iomap.

v2:
 - Move the call to flush_dcache_page (Christoph)
 - Clarify comments (Darrick)
 - Rename read_count to read_bytes_pending (Christoph)
 - Rename write_count to write_bytes_pending (Christoph)
 - Restructure iomap_readpage_actor() (Christoph)
 - Change return type of the zeroing functions from loff_t to s64

Matthew Wilcox (Oracle) (9):
  iomap: Fix misplaced page flushing
  fs: Introduce i_blocks_per_page
  iomap: Use kzalloc to allocate iomap_page
  iomap: Use bitmap ops to set uptodate bits
  iomap: Support arbitrarily many blocks per page
  iomap: Convert read_count to read_bytes_pending
  iomap: Convert write_count to write_bytes_pending
  iomap: Convert iomap_write_end types
  iomap: Change calling convention for zeroing
