Sorry, I should have done that.

blockdump.patch=20
Adds the .c and .h files for the mid-layer. It allows block drivers to
provice diskdump functionality while removing dependencies from the low
level device drivers.

cciss_diskdump.patch
This file contains the functions used by the cciss driver to perform
diskdump operations.

cciss.patch
Modifies cciss.c to include declaration of extended device operations
and modifies our sendcmd function to operate during a dump (polling vs
interrupt driven, etc)

configin.patch
Gives the user the option of adding blockdump support to cciss.

diskdump_doc.patch
Adds cciss to the list of supported devices in the README file of the
diskdumputils package.

diskdumpsh.patch
Adds support to load the required block_dump driver at boot time.

fs_h.patch
Adds a new entry to block_device_operations structure to allow drivers
to define if they support diskdump. Required by block_dump to see if the
LLDD is a valid dump device.

makefile.patch
Adds block_dump to the block layer Makefile.

README.blockdump
The README file.

Thanks,
