Hello ,
I came across the dirty-page tracking patch here:
[https://lkml.org/lkml/2011/6/21/169] .
There is some mention of dirty-bit tracking not working with EPT. Can
someone please clarify this? Does this patch only work
if intel EPT is
enabled to indicate that the dirty bits of underlying sptes are not updated by
hardware.

OK, I'll have a try over other workarounds.
I am not feeling good about need_pte_unmap myself. :-)
The usual way is to check VM_HUGETLB in the caller
