SYSFS ENTRIES
================================================================================
Information about mounted f2f2 file systems can be found in
/sys/fs/f2fs. Each mounted filesystem will have a directory in
/sys/fs/f2fs based on its device name (i.e., /sys/fs/f2fs/sda).
The files in each per-device directory are shown in table below.
