I'm trying to build the cloop module under Linux 2.6.30.5, but the compilation aborts with "compressed_loop.c:286: error: implicit declaration of function ‘blk_rq_pos’." I downloaded the source from http://debian-knoppix.alioth.debian.org/sources/ , and the sha1sum matched.

Here is my system information:
Debian 4.0/i386
Linux kernel 2.6.30.5
cloop source 2.631

I put a log of the build failure here: http://home.earthlink.net/~mumia.w.1...cloop-fail.txt

How can I get pass this error and get the cloop module built?
