well, patched 2.6.9 kernel successfully. But still unable to compile.
Compiling kernel modules:

where do i missed cluster/cnxman.h , cluster/service.h and cluster/dlm.h ?

What should be installed prior to compiling patched kernel ?

Actually i'm interested in possibility of running GFS over redhat 7.3. But if
it really hard to do, or unmaintainable, or even impossible, let's go with
more fresh distro (read compiler/glibc).

Comments are greatly appreciated.
