Weichao Guo 398c037d13 fsck.f2fs: use elapsed_time in checkpoint for period check 
We now use walltime for monthly period check. However the walltime is:
* unstable(timestamp register reset) and settable(modified by user)
* unreasonable(e.g: device power-off for one month, no data changed)

When the walltime changes to the past before one month or the future
after one month, the period check in next fsck will fail to skip or
start a full scan. So, let's use the elapsed_time in checkpoint as
current time for period check.

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.
