There are three flags that control Write Booster Feature. 1. WB ON/OFF 2. WB Hibern Flush ON/OFF (implicitly) 3. WB Flush ON/OFF (explicit) The sysfs attribute that controls the WB was implemented. (1) In the case of "Hibern Flush", it is always good to turn on. Control may not be required. (2) Finally, "Flush" may be necessary because the Auto-Hibern8 is not supported in a specific environment. So the sysfs attribute that controls this is necessary.
