We may still have inconsistent input parameters even if we choose not to merge and the vma_merge() invariant checks are useful for checking this with no production runtime cost (these are only relevant when CONFIG_DEBUG_VM is specified). Therefore, perform these checks regardless of whether we merge. This is relevant, as a recent issue (addressed in commit "mm/mempolicy: Correctly update prev when policy is equal on mbind") in the mbind logic was only picked up in the 6.2.y stable branch where these assertions are performed prior to determining mergeability. Had this remained the same in mainline this issue may have been picked up faster, so moving forward let's always check them.

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.
