I was talking about this leak 2 days back but my mail ot lost..

----

we have in vfree --> vmfree_area_pages (calling) free_area_pmd (calling) free_area_pte (calling) free_page. The final free_page frees all the pages that are allocated to a memory region in vmalloc. Now where are we freeing pages that are allocated to page table themselves. For simplicity we can assume 2 level page tables (pgd == pmd)
