Add a new LEGACY_DIRECT_IO config symbol that is only selected by the file systems that still use the legacy blockdev_direct_IO code, so that kernels without support for those file systems don't need to build the code.

This is a port of IBM's Journaled Filesystem . More information is

Posix Access Control Lists (ACLs) support permissions for users and

groups beyond the owner/group/world scheme.

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.
