[GIT PULL] iomap: new code for 5.3, part 1

["Darrick J. Wong" <djwong@kernel.org>]

Hi Linus,

Here's the first part of the iomap merge for 5.3.  There are a few fixes
for gfs2 but otherwise it's pretty quiet so far. The branch merges
cleanly against this morning's HEAD and survived an overnight run of
xfstests.  The merge was completely straightforward, so please let me
know if you run into anything weird.

For the second part of the merge window I would like to break up iomap.c
into smaller files grouped by functional area so that it'll be easier in
the long run to keep the pieces separate and to review incoming patches.
There won't be any functional changes, as the file can still be split
very cleanly.

I prefer to get this done quickly before 5.3-rc1 because I anticipate
that there will be rather more iomap development work coming for 5.4, so
my plan is to rebase my splitting series after the mm and block merges
land and come back in a week or so having let it soak in for-next for
several days.  Let me know if you'd pefer a different timeline.

----------------------------------------------------------------
New for 5.3:
- Only mark inode dirty at the end of writing to a file (instead of once
