The design has been focused on addressing the fundamental issues in LFS, which are snowball effect of wandering tree and high cleaning overhead. Since flash-based storages show different characteristics according to the internal geometry or flash memory management schemes aka [31mCONFIG_FTL[0m, F2FS and tools support various parameters not only for configuring on-disk layout, but also for selecting allocation and cleaning algorithms.

If you don't know what Access Control Lists are, say N config [31mCONFIG_F2FS_FS_SECURITY[0m bool "F2FS Security Labels" depends on [31mCONFIG_F2FS_FS_XATTR[0m help Security labels provide an access control facility to support Linux Security Models (LSMs) accepted by AppArmor, SELinux, Smack and TOMOYO Linux. This option enables an extended attribute handler for file security labels in the f2fs filesystem, so that it requires enabling the extended attribute support in advance. In particular you need this option if you use the setcap command to assign initial process capabi- lities to executables (the security.* extended attributes).
