Looking at the patch which introduces tlb_remove_page_ptdesc() [1], it seems that
tlb_remove_page_ptdesc() already calls tlb_remove_page() with ptdesc_page(pt), so
I'm not sure whether the above tlb_remove_page_ptdesc((tlb), (page_ptdesc(pte)))
is correct.
Shouldn't it just be tlb_remove_page_ptdesc((tlb), (pte))?
Thanks,
Adrian
