commit de5724ca38fd5e442bae9c1fab31942b6544012d upstream.
syzbot complains about a race in xfrm_lookup_with_ifid() [1]
When preparing commit 0a9e5794b21e ("xfrm: annotate data-race
around use_time") I thought xfrm_lookup_with_ifid() was modifying
a still private structure.
[1]

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.
