commit a53adb79711ccfc76a4ee32b20253045cdab55c7
Author: Mark Wielaard <mark@klomp.org>
Date: Mon Jul 27 16:36:17 2020 +0200
Handle linux syscalls sched_getattr and sched_setattr
The only "special" thing about these syscalls is that the given
struct sched_attr determines its own size for future expansion.
Original fix by "ISHIKAWA,chiaki" <ishikawa@yk.rim.or.jp>
