Building with some experimental patches, I came across a warning
in the tls code:
include/linux/compiler.h:215:30: warning: assignment discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
215 | *(volatile typeof(x) *)&(x) = (val); \
| ^
net/tls/tls_main.c:650:4: note: in expansion of macro 'smp_store_release'
650 | smp_store_release(&saved_tcpv4_prot, prot);
This appears to be a legitimate warning about assigning a const pointer
into the non-const 'saved_tcpv4_prot' global. Annotate both the ipv4 and
ipv6 pointers 'const' to make the code internally consistent.
Fixes: 5bb4c45d46 ("net/tls: Read sk_prot once when building tls proto ops")

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.
