The logic at the end of xchk_bmap_want_check_rmaps tries to detect a file fork that has been zapped by what will become the online inode repair code. Zapped forks are in FMT_EXTENTS with zero extents, and some sort of hint that there's supposed to be data somewhere in the filesystem. Unfortunately, the inverted logic here is confusing and has the effect that we always call xchk_bmap_check_rmaps for FMT_BTREE forks. This is horribly inefficient and unnecessary, so invert the logic to get rid of this performance problem. This has caused 8h delays in generic/333 and generic/334. Signed-off-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.
