At contains_pending_extent() the value of the end offset of a chunk we found in the device's allocation state io tree is inclusive, so when we calculate the length we pass to the in_range() macro, we must sum 1 to the expression "physical_end - physical_offset". In practice the wrong calculation should be harmless as chunks sizes are never 1 byte and we should never have 1 byte ranges of unallocated space. Nevertheless fix the wrong calculation.

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.
