Instead of checking for an end offset of (u64)-1 (U64_MAX) for the current extent state's end, and then checking after updating the current start offset if it's now beyond the range's end offset, we can simply stop if the current extent state's end is greater than or equals to our range's end offset. This helps remove one comparison under the 'next' label and allows to remove the if statement that checks if the start offset is greater than the end offset under the 'search_again' label.

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.
