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"
	depends on QUOTA && NET
	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
	bool "Print quota warnings to console (OBSOLETE)"
	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.

	help
	  This quota format was (is) used by kernels earlier than 2.4.22. If
	  you have quota working and you don't want to convert to new quota
	  format say Y here.

config QFMT_V2
	tristate "Quota format v2 support"
	depends on QUOTA
	select QUOTA_TREE
	help
	  This quota format allows using quotas with 32-bit UIDs/GIDs. If you
	  need this functionality say Y here.

	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.txt> for details.

config TMPFS_POSIX_ACL
	bool "Tmpfs POSIX Access Control Lists"
	depends on TMPFS
	select GENERIC_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.

	  hugetlbfs is a filesystem backing for HugeTLB pages, based on
	  ramfs. For architectures that support it, say Y here and read
	  <file:Documentation/vm/hugetlbpage.txt> for details.
