3 tristate "JFS filesystem support"
8 select LEGACY_DIRECT_IO
10 This is a port of IBM's Journaled Filesystem . More information is
11 available in the file <file:Documentation/admin-guide/jfs.rst>.
13 If you do not intend to use the JFS filesystem, say N.
16 bool "JFS POSIX Access Control Lists"
20 Posix Access Control Lists (ACLs) support permissions for users and
21 groups beyond the owner/group/world scheme.
23 If you don't know what Access Control Lists are, say N
26 bool "JFS Security Labels"
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.
34 If you are not using a security module that requires using
35 extended attributes for file security labels, say N.
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.
