Research direction
Start by locating the Raspberry Pi kernel configuration definitions for CONFIG_F2FS_FS_COMPRESSION and compare the settings used for the different Raspberry Pi variants. Enable the requested feature in the relevant configurations, then verify the resulting kernel configuration through /proc/config.gz and confirm that the option is no longer reported as not set.
Written by the indexing model from the issue text.
Description
Since kernel 5.6 F2FS has a transparent compression feature.
Unfortunatly even if the filesystem has been created correctly the kernel currently shipped with Raspbian/Buster it cannot be used.
As F2FS is statically compiled into the kernel and it can thus be used as root filesystem.
It would be nice to have a filesystem at hand that is a bit better suited for flash media like MMC cards. Compression does help here, too.
Please enable the feature in future kernels.
