In function scrub_handle_errored_block(), we use @sblocks_for_recheck pointer to hold one scrub_block for each mirror, and uses kcalloc() to allocate an array. But this one pointer for an array is not readable due to the member offsets done by addition and not []. Change this pointer to struct scrub_block *[BTRFS_MAX_MIRRORS], this will slightly increase the stack memory usage. Since function scrub_handle_errored_block() won't get iterative calls, this extra cost would completely be acceptable. And since we're here, also set sblock->refs and use scrub_block_put() to clean them up, as later we will add extra members in scrub_block, which needs scrub_block_put() to clean them up.

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.
