Current period of this is 3 sec and it is used when Perfetto profiling is running on Android. Without Perfetto profiling, it doesn't affect the system at all. However, 3 sec doesn't provide enough granularity to understand F2FS I/O behaviors. To make F2FS I/O profiling ftrace effective, set the ftrace period to 1 sec.
