Jeff Moyer bb232821fa dax: pass NOWAIT flag to iomap_apply
[ Upstream commit 96222d53842dfe54869ec4e1b9d4856daf9105a2 ]

fstests generic/471 reports a failure when run with MOUNT_OPTIONS="-o
dax".  The reason is that the initial pwrite to an empty file with the
RWF_NOWAIT flag set does not return -EAGAIN.  It turns out that
dax_iomap_rw doesn't pass that flag through to iomap_apply.

With this patch applied, generic/471 passes for me.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
