As long as we are clear that the latest draft of patch 1/3 is to be
taken from the v4 patch{set} and patches 2/3 and 3/3 are to be taken
from v3 of the patchset I don't think you need to do anything further.
The important bit is for the other LSM folks to ACK the new hook; if I
don't see anything from them, either positive or negative, I'll merge
it towards the end of this week or early next.
