The struct nft_pipapo_scratch is allocated, then aligned to the required alignment and difference (in bytes) is then saved in align_off. The aligned pointer is used later. While this works, it gets complicated with all the extra checks if all member before map are larger than the required alignment. Instead of saving the aligned pointer, just save the returned pointer and align the map pointer in nft_pipapo_lookup() before using it. The alignment later on shouldn't be that expensive. With this change, the align_off can be removed and the pointer can be passed to kfree() as is.

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.
