Linux kernel source tree
2f5d370dec
There are 43 instances of posix shell tests and 35 instances of bash. To give us a single consistent language for testing in, replace all #!/bin/sh to #!/bin/bash. Common sources that are included in both different shells will now work as expected. And we no longer have to fix up bashisms that appear to work when someone's system has sh symlinked to bash, but don't work on other systems that have both shells installed. Although we could have chosen sh, it's not backwards compatible so it wouldn't be possible to bulk convert without re-writing the existing bash tests. Choosing bash also gives us some nicer features including 'local' variable definitions and regexes in if statements that are already widely used in the tests. It's not expected that there are any users with only sh available due to the large number of bash tests that exist.

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 reStructuredText 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.
