* Use guard(mutex), which results in:
- the function can return directly when "space == 0".
- "i" can now be "unsigned" as it is no longer abused to hold a retval
from tty->ops->write(). Note the compared-to "nr" is already
"unsigned".
* The end label is now dubbed "do_write" as that is what happens there.
Unlike the uncertain "break_out" name.

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.
