@ -323,3 +323,18 @@ What: /sys/fs/f2fs/<disk>/mounted_time_sec
Date: February 2020
Contact: "Jaegeuk Kim" <jaegeuk@kernel.org>
Description: Show the mounted time in secs of this partition.
What: /sys/fs/f2fs/<disk>/data_io_flag
Date: April 2020
Contact: "Jaegeuk Kim" <jaegeuk@kernel.org>
Description: Give a way to attach REQ_META|FUA to data writes
given temperature-based bits. Now the bits indicate:
* REQ_META | REQ_FUA |
* 5 | 4 | 3 | 2 | 1 | 0 |
* Cold | Warm | Hot | Cold | Warm | Hot |
What: /sys/fs/f2fs/<disk>/iostat_period_ms
Date: April 2020
Contact: "Daeho Jeong" <daehojeong@google.com>
Description: Give a way to change iostat_period time. 3secs by default.
The new iostat trace gives stats gap given the period.
