EXT4_KUNIT_TESTS selects EXT4_FS, thus enabling an optional feature the
user may not want to enable. Fix this by making the test depend on
EXT4_FS instead.
Fixes: 1cbeab1b24 ("ext4: add kunit test for decoding extended timestamps")

This is the next generation of the ext3 filesystem.
|
|
|
|
Unlike the change from ext2 filesystem to ext3 filesystem,
|
|
the on-disk format of ext4 is not forwards compatible with
|
|
ext3; it is based on extent maps and it supports 48-bit
|
|
physical block numbers. The ext4 filesystem also supports delayed
|
|
allocation, persistent preallocation, high resolution time stamps,
|
|
and a number of other features to improve performance and speed
|
|
up fsck time. For more information, please see the web pages at
|
|
http://ext4.wiki.kernel.org.
|
|
|
|
The ext4 filesystem supports mounting an ext3 filesystem; while there
|
|
are some performance gains from the delayed allocation and inode
|
|
table readahead, the best performance gains require enabling ext4
|
|
features in the filesystem using tune2fs, or formatting a new
|
|
filesystem as an ext4 filesystem initially. Without explicit enabling
|
|
of ext4 features, the on disk filesystem format stays fully backward
|
|
compatible.
|
|
|
|
To compile this file system support as a module, choose M here. The
|
|
module will be called ext4.

|

If unsure, say N.
