The refactoring involves the following parts: - Introduce bytes_to_csum_size() and csum_size_to_bytes() helpers As we have quite some open-coded calculations, some of them are even split into two assignments just to fit 80 chars limit. - Remove the @csum_size parameter from max_ordered_sum_bytes() Csum size can be fetched from @fs_info. And we will use the csum_size_to_bytes() helper anyway. - Add a comment explaining how we handle the first search result - Use newly introduced helpers to cleanup btrfs_lookup_csums_range() - Move variables declaration to the minimal scope - Never mix number of sectors with bytes There are several locations doing things like: size = min_t(size_t, csum_end - start, max_ordered_sum_bytes(fs_info)); ... size >>= fs_info->sectorsize_bits Or offset = (start - key.offset) >> fs_info->sectorsize_bits; offset *= csum_size; Make sure these variables can only represent BYTES inside the function, by using the above bytes_to_csum_size() helpers.

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.
