This patch adds a readonly feature on small partitions by eliminating on-disk layout for data writes such as provisioning/reserved space and SSA. This requires f2fs updates to understand RO feature in superblock. Tested 4 cases: sload.f2fs -c -a lz0 -f kernel/fs $DEV sload.f2fs -c -a lz4 -f kernel/fs $DEV sload.f2fs -c -r -a lz4 -f kernel/fs $DEV sload.f2fs -c -L 3 -r -a lz4 -f kernel/fs $DEV after: mkfs.f2fs -O ro,compression,extra_attr -f $DEV fsck.f2fs $DEV Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

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 - pkg-config - 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.
