This patch adds bpf_sk_storage_get() and bpf_sk_storage_delete() helper to the bpf_tcp_ca's struct_ops. That would allow bpf-tcp-cc to: 1) share sk private data with other bpf progs. 2) use bpf_sk_storage as a private storage for a bpf-tcp-cc if the existing icsk_ca_priv is not big enough.

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.
