Merge branch 'urgent.2021.05.20a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu

Pull kcsan fix from Paul McKenney:
 "Fix for a regression introduced in this merge window by commit
  5381af5640fa ("kcsan, debugfs: Move debugfs file creation out of early
  init").

  The regression is not easy to trigger, requiring a KCSAN build using
  clang with CONFIG_LTO_CLANG=y. The fix is to simply make the
  kcsan_debugfs_init() function's type initcall-compatible. This has
  been posted to the relevant mailing lists:"
