I've kept it here just to better highlight this change, suggested by
Juri, since we was not entirely sure you are fine with it...

If you think it's ok adding a SCHED_FLAG_TUNE_POLICY behavior to the
sched_setattr syscall, I can certainly squash into the previous patch,
which gives more context on why we need it.

Otherwise, if we want to keep these bits better isolated for possible
future bisects, I can also move it at the beginning of the series.

What do you like best ?

Since we are at that, are we supposed to document some{where,how}
these API changes ?
