3 tristate "JFS filesystem support"
7 This is a port of IBM's Journaled Filesystem . More information is
8 available in the file <file:Documentation/admin-guide/jfs.rst>.
10 If you do not intend to use the JFS filesystem, say N.
13 bool "JFS POSIX Access Control Lists"
17 Posix Access Control Lists (ACLs) support permissions for users and
18 groups beyond the owner/group/world scheme.
20 If you don't know what Access Control Lists are, say N
23 bool "JFS Security Labels"
26 Security labels support alternative access control models
27 implemented by security modules like SELinux. This option
28 enables an extended attribute handler for file security
29 labels in the jfs filesystem.
31 If you are not using a security module that requires using
32 extended attributes for file security labels, say N.
38 If you are experiencing any problems with the JFS filesystem, say
39 Y here. This will result in additional debugging messages to be
40 written to the system log. Under normal circumstances, this
41 results in very little overhead.
47 Enabling this option will cause statistics from the JFS file system
48 to be made available to the user in the /proc/fs/jfs/ directory.
