That is understood. Typically these object where page sized though and various assumptions (pretty dangerous ones as you are finding out) are made regarding object reuse. The fallback of SLUB for higher order allocs to the page allocator avoids these problems for higher order pages.omg...I would be very thankful if you would go through the tree and check for any remaining use cases like that. Would take care of your problem.
I would be happy to do it. Do you have any example of any user that behaved like this in the past, so I can search for something similar? This can potentially take many forms, and auditing every kfree out there is not humanly possible. The best I can do is to search for known patterns here... -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
