Eric Biggers 25ab476727 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().

README.md

F2FS format utility

To use the f2fs filesystem, you should format the storage partition with this utility. Otherwise, you cannot mount f2fs.

Before compilation

You should install the following packages.

  • libuuid-devel or uuid-dev
  • autoconf
  • libtool
  • libselinux1-dev

Initial compilation

Before initial compilation, autoconf/automake tools should be run.

./autogen.sh

How to compile

./configure
make
make install

How to cross-compile (e.g., for ARM)

  1. Add the below line into mkfs/Makefile.am:
    mkfs_f2fs_LDFLAGS = -all-static

  2. Add the below line into fsck/Makefile.am:
    fsck_f2fs_LDFLAGS = -all-static

  3. then, do:
    LDFLAGS=--static ./configure
    --host=arm-none-linux-gnueabi --target=arm-none-linux-gnueabi
    make

How to run by default

mkfs.f2fs -l [LABEL] $DEV

For more mkfs options, see the man page.
