A process can get stuck in an uninterruptible wait in the kernel while destroying a cm_id when iw_cm_connect() fails: For example, When creation of a PD fails but the user continues with an attempt to connect to the server without checking the return value, in iw_cm_connect() a NULL qp is found so the call fails. However the IWCM_F_CONNECT_WAIT bit is not cleared. destroy_cm_id() then waits forever for IWCM_F_CONNECT_WAIT to be cleared. The same problem exists on the passive side with the accept call. Fix this by clearing the bit and waking up any waiters in the appropriate spots.
