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.
# Generic support for tree structured quota files. Seleted when needed.
config QUOTA_TREE
tristate
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.

depends on XFS_QUOTA || QUOTA

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.
# Generic support for tree structured quota files. Selected when needed.
config QUOTA_TREE
tristate
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.
config QUOTACTL
bool
depends on XFS_QUOTA || QUOTA
