Kernels which have F2FS support can be modified to support F2FS-ALL.
So here are some of kernels that I modified to work with F2FS-ALL.
These Kenels hv been modified from the original kernel to support F2FS for data,system and cache.
Unlike other kernels which support only data partition to be F2FS I have modified them to work with other partitions as well.
What is F2FS?
F2FS (Flash-Friendly File System) is a flash file system created by Kim Jaegeuk at Samsung for the Linux operating system kernel. The motive for F2FS was to build a file system that from the start takes into account the characteristics of NAND flash memory-based storage devices (such as solid-state disks, eMMC, and SD cards), which are widely used in computer systems ranging from mobile devices to servers.

First you shoud have F2FS-ALL supported ROM installed. Flashed through a F2FS-ALL supported recovery
1.put the downloaded kernel in ur N5
2.reboot to recovery (twrp with f2fs-all support)
When u r flashing ur rom flash the AOSP kernel always together!
Faux123 (WIFI DOESNT WORK test if it works for ur configuration and report back)
ElementalX, Zeta, Uber and Bricked Kernel will work if you download it directly from the official thread
I can bring up some more kernels to support F2FS-ALL during my free time feel free to ask
but i cant compile... so i can only mod F2FS supported kernels..
