commit: 0f1dcfae6bc5563424346ad3a03282b8235a4c33 From: Steve Wise <[email protected]> Date: Fri, 27 Apr 2012 09:59:16 -0500 Subject: RDMA/cxgb4: Always wake up waiters in c4iw_peer_abort_intr()
This fixes a race where an ingress abort fails to wake up the thread blocked in rdma_init() causing the app to hang.
