Hi Linus,
As promised, here's the second part of the iomap merge for 5.3, in which
we break up iomap.c into smaller files grouped by functional area so
that it'll be easier in the long run to maintain cohesiveness of code
units and to review incoming patches. There are no functional changes
and fs/iomap.c split cleanly.
Note that this refactoring series has been lurking in for-next during
the merge window, but I rebased the series a couple of days ago to pick
up all the fs/iomap.c changes that came in earlier in the merge window
from other trees, and now you don't have to pick up the pieces of a
somewhat messy merge collision. :)
The branch merges cleanly against this morning's HEAD (3bfe1fc46794) and
survived an overnight run of xfstests. The merge was completely
straightforward, so please let me know if you run into anything weird.
The only weirdness I've seen so far is that the new kernel header
compile test (CONFIG_KERNEL_HEADER_TEST) tries to test-compile iomap.h
even when CONFIG_BLOCK=n and fails, but that combination wouldn't work
even in regular kernel code because iomap is a support library for
filesystems that use block devices. Masahiro Yamada sent a patch
earlier today to disable the header compile test for now while he
reconsiders its strategy.

iomap: move internal declarations into fs/iomap/ (2019-07-17 07:21:02 -0700)
----------------------------------------------------------------
Also new for 5.3:
- Regroup the fs/iomap.c code by major functional area so that we can
start development for 5.4 from a more stable base.
----------------------------------------------------------------
Darrick J. Wong (8):
iomap: start moving code to fs/iomap/
iomap: move the swapfile code into a separate file
iomap: move the file mapping reporting code into a separate file
iomap: move the SEEK_HOLE code into a separate file
iomap: move the direct IO code into a separate file
iomap: move the buffered IO code into a separate file
