We see that one too, on a random set of kernels the splice from zero to
pipe succeeds. We are trying to investigate.

These are most likely missing bacports for the sysctl fixes.

Does this one still fail on a freshly rebooted machine? My guess is that
if we succeed to set invalid values in the proc_sched_rt01 it may
confuse the kernel enough to fail this test as well.
