> Not sure if you have code that can share but I can't imagine there are many places that would have a single call site in the driver doing alloc_pages() over and over again. For example, there is only two alloc_pages() in intel-iommu.c with one is only in the cold path, so even if alloc_pgtable_page() one do leaking, it is still up to there air if your patch will catch it because it may not a single call site and it needs to leak significant amount of memory to be the greatest consumer where it is just not so realistic. | ||||||||||||
