Why isnt this merged into 1 of 12? To give zero regression risk to 1/12 when MMU_NOTIFIER=y or =n and the mmu notifiers aren't registered by GRU or KVM. Keep in mind that the whole point of my proposed patch ordering from day 0, is to keep as 1/N, the absolutely minimum change that fully satisfy GRU and KVM requirements. 4/12 isn't required by GRU/KVM so I keep it in a later patch. I now moved mmu_notifier_unregister in a later patch too for the same reason. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
