help
Ext2 is a standard Linux file system for hard disks.
This filesystem driver is deprecated because it does not properly
support inode time stamps beyond 03:14:07 UTC on 19 January 2038.
Ext2 users are advised to use ext4 driver to access their filesystem.
The driver is fully compatible, supports filesystems without journal
or extents, and also supports larger time stamps if the filesystem
is created with at least 256 byte inodes.
This code is kept as a simple reference for filesystem developers.
If unsure, say N.
config EXT2_FS_XATTR
bool "Ext2 extended attributes"
depends on EXT2_FS
help
Extended attributes are name:value pairs associated with inodes by
the kernel or by users (see the attr(5) manual page for details).
If unsure, say N.
config EXT2_FS_POSIX_ACL
bool "Ext2 POSIX Access Control Lists"
depends on EXT2_FS_XATTR
select FS_POSIX_ACL
help
Posix Access Control Lists (ACLs) support permissions for users and
groups beyond the owner/group/world scheme.
If you don't know what Access Control Lists are, say N
config EXT2_FS_SECURITY
bool "Ext2 Security Labels"
depends on EXT2_FS_XATTR
help
Security labels support alternative access control models
implemented by security modules like SELinux. This option
enables an extended attribute handler for file security
labels in the ext2 filesystem.
If you are not using a security module that requires using
extended attributes for file security labels, say N.
