F2FS help

Can somebody with F2FS working test this kernel?
It's only adds patched hammerhead.fstab to ramdisk.

I cannot format /data back to ext4.

getting stock rooted Calkulin rom converted to data/cache f2fs

@Calkulin (because you uploaded the rom)
@katinatez (because you are good folk)
@zaphodbeeb (becasue you are the one that taught me to convert to mixed partitions)
hoping to get some help on this for me and others wanting to try out the update.
i am trying to get the rooted 05q to work on my mixed f2fs/etx4 partitions. data/cache f2fs - system etx4 so i don't have to wipe my /data partition.
i have gone through several routes so far to no avail. sideloading/flashing. flashing the ak 113 kernel with instructions for the new update. updated to the new katinatez philz with the new f2fs comits.
1. updater script - i did not see a need in changing the /data to use busybox for f2fs as the line of code is already there.
2. fstab.bacon - i used zaphods new f2fs all or f2fs mixed
Code:
# Android fstab file.
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

/devices/platform/xhci-hcd auto vfat defaults voldmanaged=usbdisk:auto
at first i just flashed the the new extras file (firmware modem linked with Calkulin's rom. then flashed the rom. i got stuck on the bootanimation for ten minutes.
then i thought it might be the kernel not 'jiving' with f2fs. so i sideloaded the ak_113 (on top of what i had already done) with the instructionsfrom @xlollomanx (thanks) linked from the ak kernel thread.
still.... stuck on cyanogen boot for ten minutes
then i restored my backup and sideloaded everything, ak kernel and all, from scratch.
once again... grrr. still stuck on boot animation for ten minutes.
any ideas on what i can do?

twrp.fstab HELP!!!

Hi! I'm a newbie here. I want to ask if the below code is correct for twrp.fstab? Those are the first 5 lines of twrp.fstab.
I change the following lines instead of ".../11120000.msdc0/by-name/system" to ".../11120000.msdc0/mmcblk0p23" and so on.
/dev/block/platform/mtk-msdc.0/11120000.msdc0/mmcblk0p23 /system ext4 ro wait,recoveryonly
/dev/block/platform/mtk-msdc.0/11120000.msdc0/by-name/vendor /vendor ext4 ro wait,recoveryonly
/dev/block/platform/mtk-msdc.0/11120000.msdc0/mmcblk0p25 /data f2fs noatime,nosuid,nodev,discard,noflush_merge wait,check,formattable,resize,encryptable=/dev/block/platform/mtk-msdc.0/11120000.msdc0/by-name/metadata,
/dev/block/platform/mtk-msdc.0/11120000.msdc0/mmcblk0p24 /cache ext4 noatime,nosuid,nodev,noauto_da_alloc,discard wait,check
PS. My recovery.img was ported using twrp auto porter but it can't mount system, data and cache.
