The last commit was found when I created a XRC SRQ in lock-free mode but failed to destroy it because of the refcnt check added in the previous commit. The failure was because the PAD was acquired through ibv_srq->pd in destroy_srq(), while ibv_srq->pd wasn't assigned when the SRQ was created by ibv_create_srq_ex(). So let's assign ibv_srq->pd in the common ibv_icmd_create_srq() , so that drivers can get the correct pd no matter which api the SRQ is created by.

commit fb96940fcf6f96185d407d57bcaf775ccf8f1762
|

Currently there is no way to observe whether the lock-free mode is
|
|
configured from the driver's perspective. Add debug log for this.
