28 | help | |
29 | Security labels support alternative access control models | |
30 | implemented by security modules like SELinux. This option | |
31 | enables an extended attribute handler for file security | |
32 | labels in the jfs filesystem. | |

40 | help | |
41 | If you are experiencing any problems with the JFS filesystem, say | |
42 | Y here. This will result in additional debugging messages to be | |
43 | written to the system log. Under normal circumstances, this | |
44 | results in very little overhead. | |

50 | Enabling this option will cause statistics from the JFS file system | |
51 | to be made available to the user in the /proc/fs/jfs/ directory. |
