10 If you say Y here, you will be able to set per user limits for disk
11 usage (also called disk quotas). Currently, it works for the
12 ext2, ext3, ext4, f2fs, jfs and ocfs2 file systems. Note that gfs2
13 and xfs use their own quota system. Ext3 and ext4 also support
14 journaled quotas for which you don't need to run quotacheck(8) after
15 an unclean shutdown. For further details, read the Quota mini-HOWTO,
16 available from <https://www.tldp.org/docs.html#howto>, or the
17 documentation provided with the quota tools. Probably the quota
18 support is only useful for multi user systems. If unsure, say N.

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

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

43 If you say Y here, quota subsystem will perform some additional
44 sanity checks of quota internal structures. If unsure, say N.

52 depends on QUOTA
53 help
54 This quota format was (is) used by kernels earlier than 2.4.22. If
55 you have quota working and you don't want to convert to new quota
56 format say Y here.

61 select QUOTA_TREE
62 help
63 This config option enables kernel support for vfsv0 and vfsv1 quota
64 formats. Both these formats support 32-bit UIDs/GIDs and vfsv1 format
65 also supports 64-bit inode and block quota limits. If you need this
66 functionality say Y here.
