Look at this report half a year later, it now occurs to me maybe it's about output of du -sh /overlay and Used column in output of df -hT. Will need to know how f2fs manages space.
Likely it's overprovision area reserved by f2fs for cleaner operation. mkfs.f2fs by default reserves 25 segments (50MB) for a partition of 128MB. Plus other spaces reserved for metadata and maangement, guess it's not too far from the output in the report.
Plus other spaces reserved for metadata and maangement, guess it's not too far from the output in the report.
The "plus" could be 1 segment for sb, 2 each for ckpt, sit, nat areas, 1 for ssa. 8 segments and 16MB in size.
The space reserved for cleaner and metadata etc. seems to be a de-facto requirement of f2fs design and implementation, not such room for tuning in my opinion.
