+config RELAYFS_FS
+ tristate "Relayfs file system support"
+ ---help---
+ Relayfs is a high-speed data relay filesystem designed to provide
+ an efficient mechanism for tools and facilities to relay large
+ amounts of data from kernel space to user space. It's not useful
+ on its own, and should only be enabled if other facilities that
+ need it are enabled, such as for example klog or the Linux Trace
+ Toolkit.
+
+ See <file:Documentation/filesystems/relayfs.txt> for further
+ information.
+
+ This file system is also available as a module ( = code which can be
+ inserted in and removed from the running kernel whenever you want).
+ The module is called relayfs. If you want to compile it as a
+ module, say M here and read <file:Documentation/modules.txt>.
+
+ If unsure, say N.

+config KLOG_CHANNEL

+ If you say Y to this, a relayfs channel named klog will be created
+ in the root of the relayfs file system. You can write to the klog
+ channel using klog() or klog_raw() from within the kernel or
+ kernel modules, and read from the klog channel by mounting relayfs
+ and using read(2) to read from it (or using cat). If you're not
+ sure, say N.

+ help
+ If you say Y to this, the klog channel will be automatically enabled
+ on startup. Otherwise, to turn klog logging on, you need use
+ sysctl (fs.relayfs.klog_enabled). This option is used in cases where
+ you don't actually want the channel to be written to until it's
+ enabled. If you're not sure, say Y.

- 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). CIFS maps the name of
- extended attributes beginning with the user namespace prefix
- to SMB/CIFS EAs. EAs are stored on Windows servers without the
- user namespace prefix, but their names are seen by Linux cifs clients
- prefaced by the user namespace prefix. The system namespace
- (used by some filesystems to store ACLs) is not supported at
- this time.
