+ 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.
+
+config EXT4_USE_FOR_EXT2
+ bool "Use ext4 for ext2 file systems"
+ depends on EXT4_FS
+ depends on EXT2_FS=n
+ default y
+ help
+ Allow the ext4 file system driver code to be used for ext2
+ file system mounts. This allows users to reduce their
+ compiled kernel size by using one file system driver for
+ ext2, ext3, and ext4 file systems.
+
+config EXT4_FS_POSIX_ACL
+ bool "Ext4 POSIX Access Control Lists"
+ depends on EXT4_FS
+ select FS_POSIX_ACL
+ help
+ POSIX Access Control Lists (ACLs) support permissions for users and
+ groups beyond the owner/group/world scheme.
+
+ To learn more about Access Control Lists, visit the POSIX ACLs for
+ Linux website <http://acl.bestbits.at/>.

+
+config EXT4_FS_SECURITY
+ bool "Ext4 Security Labels"
+ depends on EXT4_FS
+ help
+ Security labels support alternative access control models
+ implemented by security modules like SELinux. This option
+ enables an extended attribute handler for file security
+ labels in the ext4 filesystem.
+
+ If you are not using a security module that requires using
+ extended attributes for file security labels, say N.
+
+config EXT4_ENCRYPTION
+ bool "Ext4 Encryption"
+ depends on EXT4_FS
+ select FS_ENCRYPTION
+ help
+ Enable encryption of ext4 files and directories. This
+ feature is similar to ecryptfs, but it is more memory
+ efficient since it avoids caching the encrypted and
+ decrypted pages in the page cache.

+
+config EXT4_DEBUG
+ bool "EXT4 debugging support"
+ depends on EXT4_FS
+ help
+ Enables run-time debugging support for the ext4 filesystem.
+
+ If you select Y here, then you will be able to turn on debugging
+ with a command such as:
+ echo 1 > /sys/module/ext4/parameters/mballoc_debug
