Research direction

Start by reproducing the issue on Raspberry Pi 5 with linux-image-6.1.0-rpi8-rpi-2712 and linux-image-6.1.0-rpi8-rpi-v8, using grep f2fs /proc/filesystems and an attempted f2fs mount. Compare the reported /boot/config files with the built kernel behavior to determine why identical f2fs settings produce different support; done means f2fs is available on the Pi 5 kernel.

Description

Describe the bug

When booting the kernel linux-image-6.1.0-rpi8-rpi-2712 , f2fs is not available.
This works fine with kernel linux-image-6.1.0-rpi8-rpi-v8

The f2fs related settings in /boot/config-6.1.0-rpi8-rpi-v8 and /boot/config-6.1.0-rpi8-rpi-2712 are identical.

Steps to reproduce the behaviour

grep f2fs /proc/filesystems

Or try to mount a f2fs filesystem
