xchk_btree_check_minrecs() checks if the contents of the immediate child of a bmbt root block can fit within the root block. This check could fail on inodes with an attr fork since xfs_bmap_add_attrfork_btree() used to demote the current root node of the data fork as the child of a newly allocated root node if it found that the size of "struct xfs_btree_block" along with the space required for records exceeded that of space available in the data fork. xfs_bmap_add_attrfork_btree() should have used "struct xfs_bmdr_block" instead of "struct xfs_btree_block" for the above mentioned space requirement calculation. This commit disables the check for unoptimized (in terms of disk space usage) data fork bmbt trees since there could be filesystems in use that already have such a layout. Suggested-by: Darrick J.

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.
