| |
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. If someone who does could test it please do.
Hanna
