[0/9] THP iomap patches for 5.10

Message

Matthew Wilcox Aug. 24, 2020, 2:55 p.m. UTC

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.

I'll send another patch series later today which are the changes to
iomap which don't pay their own way until we actually have THPs in the
page cache.  I would like those to be reviewed with an eye to merging
them into 5.11.

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 byte count
  iomap: Convert write_count to byte count
  iomap: Convert iomap_write_end types
  iomap: Change calling convention for zeroing
