633488947ef6 ("kernfs: Use RCU to access kernfs_node::parent.") is a
preparatory refactor with no Fixes: or Cc: stable. It is part of a series whose
other patches are not in 6.12 either, and it has fixups upstream, so it is not
a clean backport.
What failure are you seeing on 6.12 (oops, lockdep splat, trace)? If you can
send it, we can look for the fix that addresses it directly.
