From 0f1dcfae6bc5563424346ad3a03282b8235a4c33 Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Fri, 27 Apr 2012 09:59:16 -0500 Subject: [PATCH] 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.
