Added file format file format subsystem for loop devices
The loop device module is extended by a file format subsystem to allow the
implementation of various disk file formats. The file format drivers are
implemented as own kernel modules and registered by the subsystem. The
subsystem takes control over the specified file format at loop creation and
calls the corresponding file format driver functions.
At the moment, the file format subsystem can handle ...
- read
- write
- discard
- flush
- sector size
... operations of loop devices.
The file format of each loop device can be specified by the LOOP_CONFIGURE
LOOP_SET_STATUS or LOOP_SET_STATUS64 ioctl with the corresponding data
structure loop_info or respectively loop_info64.
