To clarify - the data corruption has only been reported with 4.10 and
later kernels to my knowledge, but the code in question is used for 4.8
and later and so yakkety should also get the fix.

The patch could be applied to xenial too, but it won't make any
practical differnce there. The code is present in xenial but not built
for kernels before 4.8.
