I thought about it, but when I saw that set_dirty were called only when it was not already set as dirty where the call seams to be necessary. I just try to call xen_modified_mem only within cpu_phy_mem_set_dirty_flags but it does not work, even when I tried to clear the dirtybits. But I maybe don't do the right thing yet to clear the dirty bits -- Anthony PERARD
