Arnd Bergmann 56af94aace samples: user-trap: fix strict-aliasing warning 
I started getting warnings for this one file, though I can't see what changed
since it was originally introduced in commit fec7b66905 ("samples: add an
example of seccomp user trap").

samples/seccomp/user-trap.c: In function 'send_fd':
samples/seccomp/user-trap.c:50:11: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
   50 |         *((int *)CMSG_DATA(cmsg)) = fd;
      |          ~^~~~~~~~~~~~~~~~~~~~~~~
samples/seccomp/user-trap.c: In function 'recv_fd':
samples/seccomp/user-trap.c:83:18: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
   83 |         return *((int *)CMSG_DATA(cmsg));
      |                 ~^~~~~~~~~~~~~~~~~~~~~~~

Using a temporary pointer variable avoids the warning.

README 

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.
