Usually, to ease the review, we increment the reroll count and send all
the patch set.  Otherwise, one would have to read all the thread to find
which patch is the last.

Could you send the v4 containing the 5 patches IIRC?

This modification of patch location should appear in the commit message.

As I mentioned earlier, I am not convinced it is the right place [1].  I get
your point [2] that some are applied with the option “-p1” and other
with “-p2”.  Ludo, any recommendation?
