CONFIG_ZFTAPE: Zftape, the VFS interface

General informations

The Linux kernel configuration item CONFIG_ZFTAPE:

Help text

Normally, you want to say Y or M. DON'T say N here or you WON'T BE ABLE TO USE YOUR FLOPPY TAPE DRIVE.

The ftape module itself no longer contains the routines necessary to interface with the kernel VFS layer (i.e. to actually write data to and read data from the tape drive). Instead the file system interface (i.e. the hardware independent part of the driver) has been moved to a separate module.

To compile this driver as a module, choose M here: the module will be called zftape.

Regardless of whether you say Y or M here, an additional runtime loadable module called `zft-compressor' which contains code to support user transparent on-the-fly compression based on Ross William's lzrw3 algorithm will be produced. If you have enabled the kernel module loader (i.e. have said Y to "Kernel module loader support", above) then `zft-compressor' will be loaded automatically by zftape when needed.

Despite its name, zftape does NOT use compression by default.
