Add extra checks for item with EXTENT_DATA type. This checks the following thing: 0) Key offset All key offsets must be aligned to sectorsize. Inline extent must have 0 for key offset. 1) Item size Uncompressed inline file extent size must match item size. (Compressed inline file extent has no information about its on-disk size.) Regular/preallocated file extent size must be a fixed value. 2) Every member of regular file extent item Including alignment for bytenr and offset, possible value for compression/encryption/type. 3) Type/compression/encode must be one of the valid values. This should be the most comprehensive and strict check in the context of btrfs_item for EXTENT_DATA.

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.
