Merge tag 'core_guards_for_6.5_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue

Pull scope-based resource management infrastructure from Peter Zijlstra:
 "These are the first few patches in the Scope-based Resource Management
  series that introduce the infrastructure but not any conversions as of
  yet.

  Adding the infrastructure now allows multiple people to start using
  them.

  Of note is that Sparse will need some work since it doesn't yet
  understand this attribute and might have decl-after-stmt issues"
