The vma->flags = 1875 = 0x753
This is: VM_READ VM_WRITE VM_MAYREAD VM_MAYEXEC VM_GROWSDOWN VM_GROWSUP VM_PFNMAP

When vm_no_page was called it seems it failed on a pte check since there is no backing page structure. - 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/
