+config PRAMFS

+	depends on HAS_IOMEM
+	select CRC32
+	help
+	   If your system has a block of fast (comparable in access speed to
+	   system memory) and non-volatile RAM and you wish to mount a
+	   light-weight, full-featured, and space-efficient filesystem over it,
+	   say Y here, and read <file:Documentation/filesystems/pramfs.txt>.
+
+	   To compile this as a module,  choose M here: the module will be
+	   called pramfs.
+
+config PRAMFS_XIP

+	depends on PRAMFS && BLOCK

+	   Say Y here to enable XIP feature of PRAMFS.

+
+config PRAMFS_XATTR
+	bool "PRAMFS extended attributes"
+	depends on PRAMFS && BLOCK
+	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.

+config PRAMFS_POSIX_ACL
+	bool "PRAMFS POSIX Access Control Lists"
+	depends on PRAMFS_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 PRAMFS_SECURITY
+	bool "PRAMFS Security Labels"
+	depends on PRAMFS_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 pram filesystem.
+
+	  If you are not using a security module that requires using
+	  extended attributes for file security labels, say N.

+	help
+	  Say Y here to build a simple module to test the protection of
+	  PRAMFS. The module will be called pramfs_test.
