How did you get the SCST to compile against the current ofed 1.2.5
kernel tree? SCST svn fails with ofed 1.2.5 kernel 2.6.22 due to changes
in the SLAB routines.
Tried pruning the extra NULL arg to kmem_cache_create, and got the
attached oopses when the target tried to register the SCST template.

Thanks. I checked in with a few other changes/bug fixes.
Please test and report any problem
