The following build-error on my config:
net/ipv6/ip6mr.c: In function ‘ip6_mroute_setsockopt’:
net/ipv6/ip6mr.c:1656:14: error: unused variable ‘do_wrmifwhole’ [-Werror=unused-variable]
 1656 |         bool do_wrmifwhole;
      |              ^

Documentation/process/submitting-patches.rst:

If your patch fixes a bug in a specific commit, e.g. you found an issue using
``git bisect``, please use the 'Fixes:' tag with the first 12 characters of
the SHA-1 ID, and the one line summary.  Do not split the tag across multiple
lines, tags are exempt from the "wrap at 75 columns" rule in order to simplify
parsing scripts.  For example::

        Fixes: 54a4f0239f2e ("KVM: MMU: make kvm_mmu_zap_page() return the number of pages it actually freed")

The following ``git config`` settings can be used to add a pretty format for
outputting the above style in the ``git log`` or ``git show`` commands::

        [core]
                abbrev = 12
        [pretty]
                fixes = Fixes: %h (\"%s\")
