[ Upstream commit3764a17e31] Commit587f03deb6caused pnfs_update_layout() to stop returning ENOMEM when the memory allocation fails, and hence causes it to fall back to trying to do I/O through the MDS. There is no guarantee that this will fare any better. If we're failing the pNFS layout allocation, then we should just redirty the page and retry later.

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.
