How to enable/setup Writeback on USB Flash Drive?
Currentyly I have Linux SuSe 22.214.171.124, I format a USB flash drive in EXT3 and mount it with the option of data=writeback. But when I use dmesg, it shows: "[sdb] Assuming drive cache: write through".
The questions are:
- Is it possible to enable writeback on USB Drive? How to setup and enable it?
- Are there any different writeback meanings between in mount option and in virtual memory?
- Can the writeback parameters in /proc/sys/vm/ folder like dirty_writeback_centisecs, dirty_expire_centisecs, control writeback on USB drive?
