Keith Busch f3edcfd871 block: fix infinite loop for invalid zone append 
[ Upstream commit b82d9fa257 ]

Returning 0 early from __bio_iov_append_get_pages() for the
max_append_sectors warning just creates an infinite loop since 0 means
success, and the bio will never fill from the unadvancing iov_iter. We
could turn the return into an error value, but it will already be turned
into an error value later on, so just remove the warning. Clearly no one
ever hit it anyway.

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.
