From 3e87f4313035c86999281336582ff554e9a17bef Mon Sep 17 00:00:00 2001 From: George Spelvin Date: Wed, 27 Mar 2019 12:55:00 -0400 Subject: [PATCH] IB/qib: Delete struct qib_ivdev.qp_rnd I was checking the field to see if it needed the full get_random_bytes() and discovered it's unused. Only compile-tested, as I don't have the hardware, but I'm still pretty confident.
