There is an inconsistency in the way that _bmap_count_blocks deals with delalloc reservations -- if the specified fork is in extents format, *count is set to the total number of blocks referenced by the in-core fork, including delalloc extents. However, if the fork is in btree format, *count is set to the number of blocks referenced by the on-disk fork, which does /not/ include delalloc extents. For the lone existing caller of _bmap_count_blocks this hasn't been an issue because the function is only used to count xattr fork blocks (where there aren't any delalloc reservations). However, when scrub comes along it will use this same function to check di_nblocks against both on-disk extent maps, so we need this behavior to be consistent. Therefore, fix _bmap_count_leaves not to include delalloc extents and remove unnecessary parameters. 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.
