1 review trailer (1 from subsystem maintainers).
'net.mptcp.available_schedulers' sysctl knob is there to list available
schedulers, not to modify this list.
There are then no reasons to give write access to it.
Nothing would have been written anyway, but no errors would have been
returned, which is unexpected.
