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 file system used on some CD-ROMs and DVDs. Since the
|
|
file system is supported by multiple operating systems and is more
|
|
compatible with standard unix file systems, it is also suitable for
|
|
removable USB disks. Say Y if you intend to mount DVD discs or CDRW's
|
|
written in packet mode, or if you want to use UDF for removable USB
|
|
disks. Please read <file:Documentation/filesystems/udf.rst>.
|
|
|
|
To compile this file system support as a module, choose M here: the
|
|
module will be called udf.
|
|
|
|
If unsure, say N.
