Please use the iomap inline handling in this branch instead of
implementing it in XFS:

https://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git/log/?h=iomap-4.19-merge

It seems like your code doesn't use the page cache for inline data
at the moment, which means you'd want to always use the direct I/O
version of the code as-is.

Althought that makes me wonder how you handle memory mapped I/O, but
I guess I'll find out later.
