rds: Make rds_sock_lock BH rather than IRQ safe.
rds_sock_info() triggers locking warnings because we try to perform a local_bh_enable() (via sock_i_ino()) while hardware interrupts are disabled (via taking rds_sock_lock). There is no reason for rds_sock_lock to be a hardware IRQ disabling lock, none of these access paths run in hardware interrupt context. Therefore making it a BH disabling lock is safe and sufficient to fix this bug. Reported-by: Kumar Sanghvi <kumaras@chelsio.com> Reported-by: Josh Boyer <jwboyer@gmail.com> Signed-off-by: David S.
