Now that we've separated the startblock and CoW/shared extent domain in the incore refcount record structure, check the domain whenever we retrieve a record to ensure that it's still in the domain that we want. Depending on the circumstances, a change in domain either means we're done processing or that we've found a corruption and need to fail out. The refcount check in xchk_xref_is_cow_staging is redundant since _get_rec has done that for a long time now, so we can get rid of it. 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.
