Since you said you had reworked this, I'll just stop looking for now. But would you please make sure that this following use case is well tested before you send? 1) After machine is up, create a bogus cache 2) free that cache right away. 3) Create two more caches. The creation of the second cache fails, because kmem_cache_alloc(kmem_cache, x) returns bad values. Those bad values can take multiple forms, but the most common is a value that is equal to an already assigned value.
If you enable debugging you will see those issues right away and do not need to infer from other problems that there is an issue in the allocators. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
