Subject: kernel memory leak: freeing pagetables in vmfree_area_pages in vmalloc.c
Date: Thu, 28 Jun 2001 15:31:21 +0530 [thread overview]
Message-ID: <65256A79.00383EB6.00@sandesh.hss.hns.com> (raw)
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)
Regards
Amol
