> No Documentation/ABI/ entry for your new sysfs file/link?
This is for adding a symbolic link to a pre-existed /sys/fs/f2fs/<disk> directory and it means /sys/fs/f2fs/<mount> points to /sys/fs/f2fs/<disk>. I already added the description of this in Documentation/filesystems/f2fs.rst.

Some system daemons in Android access with the pre-defined sysfs entry name in the json file. So whenever the project changes and the partition layout is changed, we have to follow up the changes and modify /sys/fs/f2fs/<disk> name in the json file accordingly.
This will help them access all the f2fs sysfs entries consistently without requiring to know those changes.

This is for the daemon to change the mode of only F2FS with the power hint of Android.
