 FreeBSD provides built-in support for several Linux(R) file systems.
 This section demonstrates how to load support for and how to mount the supported Linux(R) file systems.
 
-=== ext2
+=== ext2 / ext3 / ext4
 
 Kernel support for ext2 file systems has been available since FreeBSD 2.2.
-In FreeBSD 8.x and earlier, the code is licensed under the GPL.
-Since FreeBSD 9.0, the code has been rewritten and is now BSD licensed.
-
-The man:ext2fs[5] driver allows the FreeBSD kernel to both read and write to ext2 file systems.
+The man:ext2fs[5] driver allows the FreeBSD kernel to both read and write to ext2, ext3, and ext4 file systems.
 
 [NOTE]
 ====
-This driver can also be used to access ext3 and ext4 file systems.
-The man:ext2fs[5] filesystem has full read and write support for ext4 as of FreeBSD 12.0-RELEASE.
-Additionally, extended attributes and ACLs are also supported, while journalling and encryption are not.
-Starting with FreeBSD 12.1-RELEASE, a DTrace provider will be available as well.
-Prior versions of FreeBSD can access ext4 in read and write mode using package:sysutils/fusefs-ext2[].
+Journalling and encryption are not supported yet.
 ====
 
-To access an ext file system, first load the kernel loadable module:
-
-[source,shell]
-....
-# kldload ext2fs
-....
-
-Then, mount the ext volume by specifying its FreeBSD partition name and an existing mount point.
+To access an ext file system, mount the ext volume by specifying its FreeBSD partition name and an existing mount point.
