commit e1da7872f6eda977bd812346bf588c35e4495a1e upstream. This patch introduces verify_blkaddr to check meta/data block address with valid range to detect bug earlier. In addition, once we encounter an invalid blkaddr, notice user to run fsck to fix, and let the kernel panic.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
