| |
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steve Wise <swise@opengridcomputing.com>
commit 0f1dcfae6bc5563424346ad3a03282b8235a4c33 upstream.
This fixes a race where an ingress abort fails to wake up the thread blocked in rdma_init() causing the app to hang.
