Masami Hiramatsu (Google) 0cb68c307e bootconfig: Fix testcase to increase max node
[ Upstream commit b69245126a ]

Since commit 6c40624930 ("bootconfig: Increase max nodes of bootconfig
from 1024 to 8192 for DCC support") increased the max number of bootconfig
node to 8192, the bootconfig testcase of the max number of nodes fails.
To fix this issue, we can not simply increase the number in the test script
because the test bootconfig file becomes too big (>32KB). To fix that, we
can use a combination of three alphabets (26^3 = 17576). But with that,
we can not express the 8193 (just one exceed from the limitation) because
it also exceeds the max size of bootconfig. So, the first 26 nodes will just
use one alphabet.

With this fix, test-bootconfig.sh passes all tests.

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.
