-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.

-config QFMT_V1
- tristate "Old quota format support"
- depends on QUOTA
- 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.

+ bool "Quota support"
+ help
+ If you say Y here, you will be able to set per user limits for disk

+ 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.
+
