From f39cc34df7ed919c5c7630a8a7a701939356c37c Mon Sep 17 00:00:00 2001 From: Mike Marciniszyn Date: Tue, 12 Apr 2016 10:45:51 -0700 Subject: IB/rdmavt: Fix adaptive pio hang The RVT_S_WAIT_PIO_DRAIN flag was missing from the set of flags indicating a qp is waiting on a resource. This caused the sleep/wakeup for adaptive pio drain to lose a wakeup "hanging" a QP.
