The allocation btree verifiers share code that is unable to detect cross-tree magic value corruptions such as a bnobt block with a cntbt magic value. Populate the b_ops->magic field of the associated verifier structures such that the structure verifier can check the magic value against the expected value based on tree type. The btree level check requires knowledge of the tree type to determine the appropriate maximum value. This was previously part of the hardcoded magic value checks. With that code removed, peek at the first magic value in the verifier to determine the expected tree type of the current block.

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.
