From a383f8ec552c9af5066eb488cc7a2d8b3994151d Mon Sep 17 00:00:00 2001 From: Dean Luick Date: Thu, 28 Jul 2016 15:21:16 -0400 Subject: [PATCH] IB/hfi1: Release node on insert failure If unable to insert node into the RB tree cache, node will be freed before returning from the function. Null out iovec's pointer to node so iovec does not try to free it later.
