SLFS is a implementation of log-structured file system designed for flash memory based storages(SSD, SD card, eMMC, …). Like other log-structured file systems, SLFS shows good performance under random write.

<Build>
1. deploy SLFS source code at your Kernel Source
# tar xzf slfs.tar.gz
# mv slfs KERNEL_SRC/fs/.
# vi KERNEL_SRC/fs/Makefile
(add following line)
obj-$(CONFIG_SLFS_FS) += slfs/
# vi KERNEL_SRC/fs/Kconfig
(find section “MISC_FILESYSTEMS” and add following line)
source "fs/slfs/Kconfig"

2. build Linux Kernel
# cd KERENL_SRC
# make menuconfig
(check SLFS as a module or built-in)
