-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.

-From cda0a857dd7a27cd5d621747464bfe71e8727fff Mon Sep 17 00:00:00 2001
-From: Daniel Kiper <daniel.kiper@oracle.com>
-Date: Tue, 29 May 2018 16:16:02 +0200
-Subject: xfs: Accept filesystem with sparse inodes
-
-The sparse inode metadata format became a mkfs.xfs default in
-xfsprogs-4.16.0, and such filesystems are now rejected by grub as
-containing an incompatible feature.
-
-In essence, this feature allows xfs to allocate inodes into fragmented
-freespace. (Without this feature, if xfs could not allocate contiguous
-space for 64 new inodes, inode creation would fail.)
-
-In practice, the disk format change is restricted to the inode btree,
-which as far as I can tell is not used by grub. If all you're doing
-today is parsing a directory, reading an inode number, and converting
-that inode number to a disk location, then ignoring this feature
-should be fine, so I've added it to XFS_SB_FEAT_INCOMPAT_SUPPORTED
-
-I did some brief testing of this patch by hacking up the regression
-tests to completely fragment freespace on the test xfs filesystem, and
-then write a large-ish number of inodes to consume any existing
-contiguous 64-inode chunk. This way any files the grub tests add and
-traverse would be in such a fragmented inode allocation. Tests passed,
-but I'm not sure how to cleanly integrate that into the test harness.
