Checking on Fedora 11 (v2.6.30), RHEL6 B1 (v2.6.32), OpenSuse 11.2 (v2.6.31), SLES 11 (v2.6.27), and Debian Lenny VMs (v2.6.35 from lio-core-2.6.git/lio-4.0), and I do see the proper /dev/bsg/H:C:T:L device nodes matching the available struct scsi_device. However, I do recall one seing the BSG H:C:T:L device nodes appear in /dev/ instead of /dev/bsg/ before. I don't recall on which environment this was, but I think it may have been some version of Ubuntu..? Just to double check on your system, a 'cat /proc/kallsyms | grep bsg' produces symbols for the kernel built-in BSG kernel code, yes..?
