[PATCH] add class support to floppy tape driver zftape-init.c
Here is a patch to add class support to zftape-init.c:
MODULE_DESCRIPTION(ZFTAPE_VERSION " - "
"VFS interface for the Linux floppy tape driver. "
"Support for QIC-113 compatible volume table "
"and builtin compression (lzrw3 algorithm)");
I have verified it compiles but do not have the hardware to test it.
