1176 JFFS2 is the second generation of the Journalling Flash File System
1177 for use on diskless embedded devices. It provides improved wear
1178 levelling, compression and support for hard links. You cannot use
1179 this on normal block devices, only on 'MTD' devices.

1189 This controls the amount of debugging messages produced by the JFFS2
1190 code. Set it to zero for use in production systems. For evaluation,
1191 testing and debugging, it's advisable to set it to one. This will
1192 enable a few assertions and will print debugging messages at the
1193 KERN_DEBUG loglevel, where they won't normally be visible. Level 2
1194 is unlikely to be useful - it enables extra debugging in certain
1195 areas which at one point needed debugging, but when the bugs were
1196 located and fixed, the detailed messages were relegated to level 2.

1921 This is the client VFS module for the Common Internet File System

1923 (SMB) protocol, the native file sharing mechanism for most early
1924 PC operating systems. The CIFS protocol is fully supported by

1926 and Windows XP) as well by Samba (which provides excellent CIFS
1927 server support for Linux and many other operating systems). Limited
1928 support for OS/2 and Windows ME and similar servers is provided as

1931 The cifs module provides an advanced network file system

1963 help
1964 Modern CIFS servers including Samba and most Windows versions
1965 (since 1997) support stronger NTLM (and even NTLMv2 and Kerberos)
1966 security mechanisms. These hash the password more securely
1967 than the mechanisms used in the older LANMAN version of the
1968 SMB protocol but LANMAN based authentication is needed to
1969 establish sessions with some old SMB servers.
1970
1971 Enabling this option allows the cifs module to mount to older
1972 LANMAN based servers such as OS/2 and Windows 95, but such
1973 mounts may be less secure than mounts using NTLM or more recent
1974 security mechanisms if you are on a public network. Unless you
1975 have a need to access old SMB servers (and are on a private
1976 network) you probably want to say N. Even if this support
1977 is enabled in the kernel build, LANMAN authentication will not be
