Subject: perf test: Check counts on all cpus in test__open_syscall_event_on_all_cpus
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d2af9687c96f3864178de1860e6d83873aeef224;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

perf test: Check counts on all cpus in test__open_syscall_event_on_all_cpus

We were bailing out after the first count mismatch, do it in all to see
if only some CPUs are not getting the expected number of events.
