[PATCH 1/9] sched: test below 0 on unsigned sysctl_sched_rt_period

[roel kluin]

Peter, you added the test in global_rt_runtime(), in commit
d0b27fa77854b149ad4af08b0fe47fe712a47ade
could you take a look at it and tell whether this test should
be replaced by something else?

The patch was only checkpatch tested
---
sysctl_sched_rt_period is unsigned so the test doesn't work.
state_filter is an unsigned long so the test didn't work
