When a rebind is skipped, we must set the max pte size of the newly
created vma to value of the old vma as we do not pte walk for the new
vma. Without this future rebinds may be incorrectly skipped due to the
wrong max pte size. Null binds are more likely to expose this bug as
larger ptes are more frequently used compared to normal bindings.

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.
