[ofa-general] Race condition in core/sysfs.c (kernel panic) when unloading the driver

I suspect that at some point in the 2+ years since 2.6.18 more locking
was added to sysfs so that this race no longer exists.  You could try
and see if my test (add a sleep to the show method and make sure you
remove the low-level driver during that window) results in an instant
crash with the RHEL 5.2 kernel.
