Currently, it works for the 13 ext2, ext3, ext4, jfs, ocfs2 and reiserfs file systems. 14 Note that gfs2 and xfs use their own quota system. 15 Ext3, ext4 and reiserfs also support journaled quotas for which 16 you don't need to run quotacheck(8) after an unclean shutdown. 17 For further details, read the Quota mini-HOWTO, available from 18 <https://www.tldp.org/docs.html#howto>, or the documentation provided 19 with the quota tools. Probably the quota support is only useful for 20 multi user systems.

Please use notification via netlink socket instead. 39 40config QUOTA_DEBUG 41 bool "Additional quota sanity checks" 42 depends on QUOTA 43 default n 44 help 45 If you say Y here, quota subsystem will perform some additional 46 sanity checks of quota internal structures.

Both these formats support 32-bit UIDs/GIDs and vfsv1 format 67 also supports 64-bit inode and block quota limits. If you need this 68 functionality say Y here. 69 70config QUOTACTL 71 bool 72 default n
