mkfs.f2fs: catch total_zones=0 instead of crashing Cleanly report an error instead of dividing by 0 (causing a floating point exception) in the following case: truncate -s 16M img && mkfs.f2fs img Note that this is a minimal fix; it appears that overly-small images still cause various integer overflows in f2fs_prepare_super_block().
