[rds-devel] [git pull] IB device refcounting

[Zach Brown]

Hey Andy, let's give our first git pull a try!

I've tested this against repeated cycles of rmmod and insmod.  It sometimes takes quite a while, but the connections do come back.  Testing did shake out some thinkos in the patches, and found other bugs like the c_cm_lock leak, so I think it's in good shape.

The following changes since commit a6ac2d0618db6b94d31ade2c906ac6519dd106fc:
  Andy Grover (1):
        RDS: use get_user_pages_fast()

      RDS/IB: get the xmit max_sge from the RDS IB device on the connection
      RDS/IB: add refcount tracking to struct rds_ib_device
      RDS: introduce rds_conn_connect_if_down()
