Subject: [PATCH 01/12] IB/rdmavt: Fix adaptive pio hang
Date: Tue, 12 Apr 2016 10:45:51 -0700 [thread overview]
Message-ID: <20160412174549.19295.98346.stgit@scvm10.sc.intel.com> (raw)
In-Reply-To: <20160412173504.19295.7241.stgit-9QXIwq+3FY+1XWohqUldA0EOCMrvLtNR@public.gmane.org>
From: Mike Marciniszyn <mike.marciniszyn-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
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.
