37 Sleeping lock types:
46 On PREEMPT_RT kernels, these lock types are converted to sleeping locks:
512 - Lock types of the same lock category (sleeping, CPU local, spinning)
516 - Sleeping lock types cannot nest inside CPU local and spinning lock types.
518 - CPU local and spinning lock types can nest inside sleeping lock types.
