Currently btrfs_verify_data_csum() just passes the whole page to check_data_csum(), which is fine since we only support sectorsize == PAGE_SIZE. To support subpage, we need to properly honor per-sector checksum verification, just like what we did in dio read path. This patch will do the csum verification in a for loop, starts with pg_off == start - page_offset(page), with sectorsize increase for each loop. For sectorsize == PAGE_SIZE case, the pg_off will always be 0, and we will only loop once. For subpage case, we do the iterate over each sector and if we found any error, we return error.

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.
