[ Upstream commitde3544d2e5] Interval tree uses [start, end] as a region which stores in the tree. In raid1, it uses the wrong end value. For example: bio(A,B) is too big and needs to be split to bio1(A,C-1), bio2(C,B). The region of bio1 is [A,C] and the region of bio2 is [C,B]. So bio1 and bio2 overlap which is not right. Fix this problem by using right end value of the region.

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.
