In a meeting with lagarcia, I was informed this patch is very important, and
that it is already on kernel 4.18-15 onwards.
In fact, including this one. there are two important patches on this
subject:
** Description changed:

Public bug reported:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly
There seems to be a mistype in the build flags; haven't checked whether
it fixes the bug though.
