[PATCH 10/40] tools include uapi: Grab a copy of linux/sched.h

From: Arnaldo Carvalho de Melo
Date: Wed Jul 26 2017 - 10:18:57 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

So that we make sure we have recent enough defines for things
such as 'perf trace' system call argument beautifiers.

For instance, the 'clone' syscall argument 'flag' needs to use
CLONE_NEWCGROUP, and that is not available in RHEL7.
