, thus improving the speed.4.0.14. Support for nanosecond-level timestamps The timestamp of the extended file system before Ext4 is in seconds, which can cope with most settings, but with the speed and integration of the processor (multi-core processor) increasing, and Linux began to develop into other application fields, it will increase the timestamp unit to the nanosecond. Ext4 adds two bits to the time range so that the time life is prolonged by 500. The date supported by the Ext4 timestamp
