Maybe, the solution is below
... // >>> ptep_clear((__vma)->vm_mm, __address, __ptep); // >>> flush_tlb_page(__vma, __address); // >>> __ptep; ...
And even so, we also get a pte with present = 0 AND its dirty = 1, an odd pte.
Remember B dirtied the pte before A executes flush_tlb_page. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
