	help
	  Ext4dev is a predecessor filesystem of the next generation
	  extended fs ext4, based on ext3 filesystem code. It will be
	  renamed ext4 fs later, once ext4dev is mature and stabilized.

	  Unlike the change from ext2 filesystem to ext3 filesystem,
	  the on-disk format of ext4dev is not the same as ext3 any more:
	  it is based on extent maps and it supports 48-bit physical block
	  numbers. These combined on-disk format changes will allow
	  ext4dev/ext4 to handle more than 16 TB filesystem volumes --
	  a hard limit that ext3 cannot overcome without changing the
	  on-disk format.

	  Other than extent maps and 48-bit block numbers, ext4dev also is
	  likely to have other new features such as persistent preallocation,
	  high resolution time stamps, and larger file support etc.  These
	  features will be added to ext4dev gradually.

	  To compile this file system support as a module, choose M here. The
	  module will be called ext4dev.

	  If unsure, say N.

config EXT4DEV_FS_XATTR
	bool "Ext4dev extended attributes"
	depends on EXT4DEV_FS
	default y
	help
	  Extended attributes are name:value pairs associated with inodes by
	  the kernel or by users (see the attr(5) manual page, or visit
	  <http://acl.bestbits.at/> for details).

	  If unsure, say N.

	  You need this for POSIX ACL support on ext4dev/ext4.

config EXT4DEV_FS_POSIX_ACL
	bool "Ext4dev POSIX Access Control Lists"
	depends on EXT4DEV_FS_XATTR
	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/>.

	  If you don't know what Access Control Lists are, say N

config EXT4DEV_FS_SECURITY
	bool "Ext4dev Security Labels"
	depends on EXT4DEV_FS_XATTR
	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 ext4dev/ext4 filesystem.

	  If you are not using a security module that requires using
	  extended attributes for file security labels, say N.
