currently matchinfo gets stored in the expression, but some xt matches are very large. To handle those we either need to switch nft core to kvmalloc and increase size limit, or allocate the info blob of large matches separately. This does the latter, this limits the scope of the changes to nft_compat. I picked a threshold of 192, this allows most matches to work as before and handle only few ones via separate alloation (cgroup, u32, sctp, rt).

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
