First thank you Namidairo for this great ROM.
It works very well. No problem at all.
I tried recently to format cache & data partition with F2FS file system.
For that I used TWRP 2.7.Voyager v1.2 using: mkfs.f2fs - t 0 /dev/block/mmcblk0p2 and over mmcblk0p8
Partition format successful but my system wont boot.
I then reformat with ext4 and system boot after.
I though that Namidairo kernel was supporting F2FS file system.
Did I do something wrong with the formatting or did I missed a step to enable F2FS?
