*	kernel: Create UBIFS v5 volume	Hauke Mehrtens	2020-08-11	1	-63/+0
\| \| \| \| \| \| \| \| \| \| \| \| \|	In commit 87b35c16adcf ("kernel: ubifs: create use file system format 4 by default") we changed the default UBIFS version used when the kernel creates a new volume from 5 to 4. UBIFS v5 was added in kernel 4.10 and only kernel 4.10 and later can read it. We changed the kernel to create version 4 volumes also on more recent kernel versions to make it possible to downgrade to an OpenWrt version with kernel 4.9, the upgrade still works. This is probably not needed any more and we can remove this patch. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
*	kernel: ubifs: create use file system format 4 by default	Hauke Mehrtens	2018-02-13	1	-0/+63
	Instead of creating an ubifs file system with format version 5 by default on empty UBI volumes use the older format 4 by default. This will make it possible to mount these file systems also on older kernel versions. When a user wants to do a sysupgrade from kernel 4.14 to kernel 4.9 the old kernel has to read the file system created by the more recent kernel which currently does not work for ubifs. This fixes the problem by creating file systems which are compatible with older kernel versions by default. Kernel 4.14 will still be able to read and write UBI FS file system version 5, it will just not be used when a ubifs partition is created implicitly on an empty UBI volume.
