A filesystem that uses the raid stripe tree for logical to physical address translation can't use the regular scrub path, that reads all stripes and then checks if a sector is unused afterwards. When using the raid stripe tree, this will result in lookup errors, as the stripe tree doesn't know the requested logical addresses. In case we're scrubbing a filesystem which uses the RAID stripe tree for multi-device logical to physical address translation, perform an extra block mapping step to get the real on-disk stripe length from the stripe tree when scrubbing the sectors. This prevents a double completion of the btrfs_bio caused by splitting the underlying bio and ultimately a use-after-free.

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.
