During the inode btree scrubs we try to confirm the freemask bits against the inode records. If the inode buffer read fails, this is a cross-referencing error, not a corruption of the inode btree itself. Use the xref_process_error call here. Found via core.version middlebit fuzz in xfs/415. The userspace xfs_scrub program will try to repair outright corruptions in the agi/inobt prior to phase 3 so that the inode scan will proceed. If only a cross-referencing error is noted, the repair program defers the repair attempt until it can check the other space metadata at least once. It is therefore essential that the inobt scrubber can correctly distinguish between corruptions and "unable to cross-reference something else with this inobt". Signed-off-by: Darrick J.

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.
