When xfs_scrub encounters a directory with a leaf1 block, it tries to validate that the leaf1 block's bestcount (aka the best free count of each directory data block) is the correct size. Previously, this author believed that comparing bestcount to the directory isize (since directory data blocks are under isize, and leaf/bestfree blocks are above it) was sufficient. Unfortunately during testing of online repair, it was discovered that it is possible to create a directory with a hole between the last directory block and isize. The directory code seems to handle this situation just fine and xfs_repair doesn't complain, which effectively makes this quirk part of the disk format. Fix the check to work properly.

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.
