The file3 and file4 are logs of normal 10times test which enabled ext3, 
ext4 in configuration.

The file1 and file2 are logs after enabling Kernel Function Tracer and 
Trace syscalls
...debug/tracing/events/spi/enable is not showed in default config.
Could you please tell me the correct way to get ftrace logs?

Thank you!
Hiep.
