CONFIG_F2FS_FS_COMPRESSION is not set #231

Closed j0ju closed 3 years ago

j0ju commented 3 years ago

Since kernel 5.6 F2FS has a transparent compression feature. Unfortunatly even if the filesystem has been created correctly the kernel currently shipped with RaspbianOS/Buster it cannot be used. As F2FS is statically compiled into the kernel and it can thus be used a ROOTFS 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.

The same applies to kernels for other Raspberry Pi variants.

Please report the issue here - https://github.com/raspberrypi/linux

They'll want a comparison of memory usage with and without the driver built in.
