We never seemed to reach completion here?Well, I'm waiting for other people comments too... as I said earlier, I'm not too fan of burrying the update_mmu_cache() inside ptep_set_access_flags(), but perhaps we could remove the whole logic of reading the old PTE & comparing it, and instead have ptep_set_access_flags() do that locally and return to the caller wether a change occured that requires update_mmu_cache() to be called. That way, archs who don't actually need update_mmu_cache() under some circumstances will be able to return 0 there. What do you guys thing ?I think that's a good idea.
I agree. Hugh
