+config PRAMFS
+ tristate "Persistent and Protected RAM file system support"
+ 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
+ bool "Execute-in-place in PRAMFS"

+ Say Y here to enable XIP feature of PRAMFS.

+ help
+ Say Y here to enable the write protect 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.

+config PRAMFS_TEST_MODULE
+ tristate "PRAMFS Test"
+ depends on PRAMFS && PRAMFS_WRITE_PROTECT && m

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