The number of blocks on the filesystem (as a percentage of the
|
|
total number of blocks), that are reserved for use by root.
|
|
Traditionally, this has been 5%, and all ext-related tools still
|
|
default to reserving 5% when creating a new ext filesystem.

Specify a space-separated list of mke2fs options, including any

ext2/3/4 filesystem features.
|
|
|
|
For more information about the mke2fs options, see the manual
|

page mke2fs(8).
|
|
|
|
For more information about the ext2/3/4 features which can be
|
|
set, see the manual page ext4(5).
|
|
|
|
The default is "-O ^64bit", i.e. disable 64-bit filesystem
|
|
support. This default value has been chosen because U-Boot
|
|
versions before 2017.02 don't support this filesystem
|
|
option: using it may make the filesystem unreadable by
|
|
U-Boot.
