Description Andrey Konovalov 2023-12-25 15:42:20 UTC 
Currently, the stack depot code uses the maximum number of hash table buckets STACK_BUCKET_NUMBER_ORDER_MAX when KASAN is enabled, as KASAN saves a large amount of stack traces.

We might want to use STACK_BUCKET_NUMBER_ORDER_MAX with KMSAN as well, for the same reason.
