	  Btrfs is a new filesystem with extents, writable snapshotting,
	  support for multiple devices and many more features.

	  Btrfs is highly experimental, and THE DISK FORMAT IS NOT YET
	  FINALIZED.  You should say N here unless you are interested in
	  testing Btrfs with non-critical data.

	  To compile this file system support as a module, choose M here. The
	  module will be called btrfs.

	  If unsure, say N.

config QUOTA
	bool "Quota support"
	help
	  If you say Y here, you will be able to set per user limits for disk
	  usage (also called disk quotas). Currently, it works for the
	  ext2, ext3, and reiserfs file system. ext3 also supports journalled
	  quotas for which you don't need to run quotacheck(8) after an unclean
	  shutdown.
	  For further details, read the Quota mini-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>, or the documentation provided
	  with the quota tools. Probably the quota support is only useful for
	  multi user systems. If unsure, say N.

config QUOTA_NETLINK_INTERFACE
	bool "Report quota messages through netlink interface"

	help
	  If you say Y here, quota warnings (about exceeding softlimit, reaching
	  hardlimit, etc.) will be reported through netlink interface. If unsure,
	  say Y.

config PRINT_QUOTA_WARNING

	depends on QUOTA
	default y
	help
	  If you say Y here, quota warnings (about exceeding softlimit, reaching
	  hardlimit, etc.) will be printed to the process' controlling terminal.
	  Note that this behavior is currently deprecated and may go away in
	  future. Please use notification via netlink socket instead.
