-Subject: fs: Add F2FS support
-
-"F2FS (Flash-Friendly File System) is flash-friendly file system which was merged
-into Linux kernel v3.8 in 2013.
-
-The motive for F2FS was to build a file system that from the start, takes into
-account the characteristics of NAND flash memory-based storage devices (such as
-solid-state disks, eMMC, and SD cards).
-
-F2FS was designed on a basis of a log-structured file system approach, which
-remedies some known issues of the older log structured file systems, such as
-the snowball effect of wandering trees and high cleaning overhead. In addition,
-since a NAND-based storage device shows different characteristics according to
-its internal geometry or flash memory management scheme (such as the Flash
-Translation Layer or FTL), it supports various parameters not only for
-configuring on-disk layout, but also for selecting allocation and cleaning
-algorithm.", quote by https://en.wikipedia.org/wiki/F2FS.
-
-The source codes for F2FS are available from:
