3.11 kernel: perf samples too long (2501 > 2500), loweringkernel.perf_event_max_sample_rate to 50000

[Justin Piszcz]

Hello,

I recent upgraded from 3.10 to 3.11 and see these on occasion in the kernel log:

perf samples too long (2501 > 2500), lowering
kernel.perf_event_max_sample_rate to 50000
perf samples too long (5040 > 5000), lowering
kernel.perf_event_max_sample_rate to 25000

I was curious what is causing this/recommendation to fix this problem?

Thanks,

Justin.
