BTRFS has the implicit assumption that a checksum in btrfs_orderd_sums is 4 bytes. While this is true for CRC32C, it is not for any other checksum. Change the data type to be a byte array and adjust loop index calculation accordingly. This includes moving the adjustment of 'index' by 'ins_size' in btrfs_csum_file_blocks() before dividing 'ins_size' by the checksum size, because before this patch the 'sums' member of 'struct btrfs_ordered_sum' was 4 Bytes in size and afterwards it is only one byte.

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.
