Hi Alexandre,

I have no plans to still pick up the series for 6.3. The patches
all look fine to me, but it's clearly too late now. What is the
actual dependency for KASAN, do you just need a longer command
line or something else? If it's just the command line size,
I would suggest that Palmer can still pick up a oneline change
to increase it and refer to this thread in the changelog as a
reference for why it is not an actual UAPI break.
