Some vars are redefined in different places. Best to avoid this classical Bash pitfall where variables are accidentally overridden by other functions because the proper scope has not been defined. Most issues are with loops: typically 'i' is used in for-loops but if it is not global, calling a function from a for-loop also doing a for-loop with the same non local 'i' variable causes troubles because the first 'i' will be assigned to another value. To prevent such issues, the iterator variable is now declared as local just before the loop. If it is always done like this, issues are avoided. To distinct between local and non local variables, all non local ones are defined at the beginning of the script. The others are now defined with the "local" keyword.

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.
