I found a following comment for raw command in
"util-linux-2.10m/disk-utils/Makefile".

# raw.c does not compile on 2.2.*.
# find out later where it does and add tests to config

But util-linux-2.10c-rhconfig.patch contains following lines.

 # If HAVE_FDUTILS is set to "yes", then setfdprm won't be installed.
 HAVE_FDUTILS=no

I think ADD_RAW should NOT be set for 2.2.x kernel.
