There's no need to allocate memory and copy from both the destination and source extent buffers to compare if the items are equal, we can instead use memcmp_extent_buffer() which allows to do only one memory allocation and copy instead of two. So use memcmp_extent_buffer() instead of memcmp(), allowing us to avoid one memory allocation, which can fail or be slow while under memory heavy pressure, avoid the memory copying and reducing code.

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 reStructuredText 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.
