This patch only refactors the existing sockmap code. This will allow
much of the psock initialization code path and bpf helper codes to
work for both sockmap bpf map types that are backed by an array, the
currently supported type, and the new hash backed bpf map type
sockhash.
Most the fallout comes from three changes,
- Pushing bpf programs into an independent structure so we
can use it from the htab struct in the next patch.
- Generalizing helpers to use void *key instead of the hardcoded
u32.
- Instead of passing map/key through the metadata we now do
the lookup inline. This avoids storing the key in the metadata
which will be useful when keys can be longer than 4 bytes. We
rename the sk pointers to sk_redir at this point as well to
avoid any confusion between the current sk pointer and the
redirect pointer sk_redir.

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.
