This is a port of IBM's Journaled Filesystem . More information is available in the file <file:Documentation/filesystems/jfs.txt>. If you do not intend to use the JFS filesystem, say N.
Posix Access Control Lists (ACLs) support permissions for users and groups beyond the owner/group/world scheme. To learn more about Access Control Lists, visit the Posix ACLs for Linux website <http://acl.bestbits.at/>. If you don't know what Access Control Lists are, say N
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 jfs filesystem. If you are not using a security module that requires using extended attributes for file security labels, say N.
If you are experiencing any problems with the JFS filesystem, say Y here. This will result in additional debugging messages to be written to the system log. Under normal circumstances, this results in very little overhead.
Enabling this option will cause statistics from the JFS file system to be made available to the user in the /proc/fs/jfs/ directory.
