The rmap btree scrubber doesn't contain sufficient checking for records that cannot overlap but do anyway. For the other btrees, this is enforced by the inorder checks in xchk_btree_rec, but the rmap btree is special because it allows overlapping records to handle shared data extents. Therefore, enhance the rmap btree record check function to compare each record against the previous one so that we can detect overlapping rmap records for space allocations that do not allow sharing.

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.
