+	  Direct Access (DAX) can be used on memory-backed block devices.
+	  If the block device supports DAX and the filesystem supports DAX,
+	  then you can avoid using the pagecache to buffer I/Os.  Turning
+	  on this option will compile in support for DAX; you will need to
+	  mount the filesystem using the -o dax option.
+
+	  If you do not have a block device that is capable of using this,
+	  or if unsure, say N.  Saying Y will increase the size of the kernel
+	  by about 5kB.

+	help
+	  Tmpfs is a file system which keeps all files in virtual memory.
+
+	  Everything in tmpfs is temporary in the sense that no files will be
+	  created on your hard drive. The files live in memory and swap
+	  space. If you unmount a tmpfs instance, everything stored therein is
+	  lost.
+
+	  See <file:Documentation/filesystems/tmpfs.txt> for details.

+	select FS_POSIX_ACL
+	help
+	  POSIX Access Control Lists (ACLs) support additional access rights
+	  for users and groups beyond the standard owner/group/world scheme,
+	  and this option selects support for ACLs specifically for tmpfs
+	  filesystems.
+
+	  If you've selected TMPFS, it's possible that you'll also need
+	  this option as there are a number of Linux distros that require
+	  POSIX ACL support under /dev for certain features to work properly.
+	  For example, some distros need this feature for ALSA-related /dev
+	  files for sound to work properly.  In short, if you're not sure,
+	  say Y.
+
+config TMPFS_XATTR
+	bool "Tmpfs extended attributes"
+	depends on TMPFS
+	default n
+	help
+	  Extended attributes are name:value pairs associated with inodes by
+	  the kernel or by users (see the attr(5) manual page for details).
+
+	  Currently this enables support for the trusted.* and
+	  security.* namespaces.
+
+	  You need this for POSIX ACL support on tmpfs.
