Hello it was pointed out to me that in the 3.7 kernel (more specifically, 3581fe0ef37ce12ac7a4f74831168352ae848edc ) a change was made in the ARM architecture to change how PERF_EVENT_IOC_PERIOD is handled.
Unlike other architectures, post-3.7 ARM updates the period right away rather than waiting until the next overflow. I can't find any discussion as to why this change was made. Should other architectures be updated to? I just wanted to find out the rationale for this before I update the manpage to reflect the difference in behaviors between architectures.
