** Description changed:

A new regression test case "sched_rr_get_interval01" for commit 975e155ed873
("sched/rt: Show the 'sched_rr_timeslice' SCHED_RR timeslice tuning knob in
milliseconds"). Has been added to the LTP syscalls test suite.

This patch can be cherry-picked in to the affected Xenial kernel. It's
already been applied in newer kernels.

Test kernel can be found here:
https://people.canonical.com/~phlin/kernel/lp-1886890-sched_rr_get_interval01/
With the patch applied, this test will pass without any issue.

+ And it can be simply tested with:
+ # echo 100 > /proc/sys/kernel/sched_rr_timeslice_ms
+ # cat /proc/sys/kernel/sched_rr_timeslice_ms
+ 100
+ (was 25 before the patch)
