For the backtrace scenario I posted it seems like it might actually be release_pages(). There seems to be a plausible call chain: __ClearPageLRU release_pages free_pages_and_swap_cache tlb_flush_mmu tlb_remove_page zap_pte_range Does that seem right? In this case, tlb_remove_page() is called right after page_remove_rmap() which ultimately results in clearing the PageAnon bit.
That is right - and pinpoints the fault for the memory leak on some third party code that fails to release a refcount on memory pages. -- All rights reversed. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
