Logan Gunthorpe b9f91d80de md/raid5: Fix sectors_to_do bitmap overflow in raid5_make_request()
For unaligned IO that have nearly maximum sectors, the number of stripes
will end up being one greater than the size of the bitmap. When this
happens, the last stripe in the IO will not be processed as it should
be, resulting in data corruption.

However, this is not normally seen when the backing block devices have
4K physical block sizes since the block layer will split the request
before that happens.

To fix this increase the bitmap size by one bit and ensure the full
number of stripes are checked when calling find_first_bit().

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.
