+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:
+
+http://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs.git
+http://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs-tools.git
+
+This patch has been integrated in OpenMandriva Lx 3.
