description |
Description: cpum_sf: ensure sample freq is non-zero
Symptom: A kernel crash might occur.
Problem: An FP divide exception during the sample rate
initialization for the hardware sampling facility.
Solution: Ensure that the sample frequency of the perf
event attribute is non-zero.
Reproduction: Run trinity against the perf_event_open() syscall.
Upstream-ID: 4bbaf2584b86b0772413edeac22ff448f36351b1
