Subject: [GIT PULL] iomap: new code for 5.20, part 1

Hi Linus,

Please pull this first branch containing new code for iomap for
5.20.  The most notable change in the first batch is that we no longer
schedule pages beyond i_size for writeback, preferring instead to let
truncate deal with those pages.

Next week, there may be a second pull request to remove iomap_writepage
from the other two filesystems (gfs2/zonefs) that use iomap for buffered
IO.  This follows in the same vein as the recent removal of writepage
from XFS, since it hasn't been triggered in a few years; it does nothing
during direct reclaim; and as far as the people who examined the
patchset can tell, it's moving the codebase in the right direction.
However, as it was a late addition to for-next, I'm holding off on that
section for another week of testing to see if anyone can come up with a
solid reason for holding off in the meantime.

As usual, I did a test-merge with upstream master as of a few minutes
ago, and didn't see any conflicts.  Please let me know if you encounter
any problems.
