Using f2fs

I see the file systems are ext4 and when I was still active @ XDA (RazrHD) custom ROMs ended up moving to Samsung’s file system (F2FS) from ext3/4 for speed, wear & tear, etc. Is that feasible here? All we had to do was add kernel support to the recovery & OS in order to format and use it (generalization, but you get the idea.)

Not with the current kernel we are using, when we move to mainline then things like this could be looked at.
