We can simplify a lot of these functions where we have to cycle through
extent_state's by simply using next_state() instead of rb_next(). In
many spots this allows us to do things like
while (state) {
/* whatever */
state = next_state(state);
}
instead of
while (1) {
state = rb_entry(n, struct extent_state, rb_node);
n = rb_next(n);
if (!n)
break;
}

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.
