If you are able to get that accepted, it will only work on linux
systems running such recent kernels. For your own systems, you can
of course do whatever you wish. But for public availability you
will then need to wait several years until your target linux users
can be expected to have moved to a suitable kernel (presumably the
*next* long-term stable kernel after the change is accepted : I
guess that version is perhaps the best part of a year away even if
your change got accepted into 4.8, and then you need your users'
distros to move to it).
To me, that doesn't seem worth the trouble (to you) of coding it,
getting it reviewed and eventually accepted, and then fixing up
whatever problems arise after it gets into linux-next [ problems
will always appear, even if the new code turns out not to be the
And first, you have to persuade somebody influential that this is a
good thing to do, particularly when people have suggested
alternative approaches. I don't count, but at the moment I've not
seen any good reasons why the kernel should be changed to support
