+	help
+	  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.
+
+	  For a DAX device to support file system access it needs to have
+	  struct pages.  For the nfit based NVDIMMs this can be enabled
+	  using the ndctl utility:
+
+		# ndctl create-namespace --force --reconfig=namespace0.0 \
+			--mode=fsdax --map=mem
+
+	  See the 'create-namespace' man page for details on the overhead of
+	  --map=mem:
+	  https://docs.pmem.io/ndctl-user-guide/ndctl-man-pages/ndctl-create-namespace
+
+          For ndctl to work CONFIG_DEV_DAX needs to be enabled as well. For most
+	  file systems DAX support needs to be manually enabled globally or
+	  per-inode using a mount option as well.  See the file documentation in
+	  Documentation/filesystems/dax.rst for details.
+
+	  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.rst> for details.
+
+config TMPFS_POSIX_ACL
+	bool "Tmpfs POSIX Access Control Lists"
+	depends on TMPFS
+	select TMPFS_XATTR
+	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).
+
+	  This enables support for the trusted.*, security.* and user.*
+	  namespaces.
+
+	  You need this for POSIX ACL support on tmpfs.
+
+	  If unsure, say N.
+
+config TMPFS_INODE64
+	bool "Use 64-bit ino_t by default in tmpfs"
+	depends on TMPFS && 64BIT
+	default n
+	help
+	  tmpfs has historically used only inode numbers as wide as an unsigned
+	  int. In some cases this can cause wraparound, potentially resulting
+	  in multiple files with the same inode number on a single device. This
+	  option makes tmpfs use the full width of ino_t by default, without
+	  needing to specify the inode64 option when mounting.
+
+	  But if a long-lived tmpfs is to be accessed by 32-bit applications so
+	  ancient that opening a file larger than 2GiB fails with EINVAL, then
+	  the INODE64 config option and inode64 mount option risk operations
+	  failing with EOVERFLOW once 33-bit inode numbers are reached.
+
+	  To override this configured default, use the inode32 or inode64
+	  option when mounting.
+
+	  If unsure, say N.
+
+config TMPFS_QUOTA
+	bool "Tmpfs quota support"
+	depends on TMPFS
+	select QUOTA
+	help
+	  Quota support allows to set per user and group limits for tmpfs
+	  usage.  Say Y to enable quota support. Once enabled you can control
+	  user and group quota enforcement with quota, usrquota and grpquota
+	  mount options.
+
+	  If unsure, say N.
