NeilBrown 34c96507e8 dm verity fec: fix GFP flags used with mempool_alloc()
mempool_alloc() cannot fail for GFP_NOIO allocation, so there is no
point testing for failure.

One place the code tested for failure was passing "0" as the GFP
flags.  This is most unusual and is probably meant to be GFP_NOIO,
so that is changed.

Also, allocation from ->extra_pool and ->prealloc_pool are repeated
before releasing the previous allocation.  This can deadlock if the code
is servicing a write under high memory pressure.  To avoid deadlocks,
change these to use GFP_NOWAIT and leave the error handling in place.

README

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

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
