At least from looking at the code, it looks like unloading the device 
driver with connections on the passive side should hang.  I'm updating 
my test code to verify that this is the case, but can you confirm that 
this problem is easily reproducible using RDS?

I'm guessing that most of my device removal testing was always done from 
the active side, and none of the mainline kernel ULPs call 
rdma_listen().  I'm hoping this would explain why this bug has gone 
undetected for this long.
