From 8d02bd8d4a6c5a9173405a0cf36751a880671235 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 14 Aug 2018 11:46:08 +0300 Subject: [PATCH] perf auxtrace: Fix queue resize commit 99cbbe56eb8bede625f410ab62ba34673ffa7d21 upstream. When the number of queues grows beyond 32, the array of queues is resized but not all members were being copied. Fix by also copying 'tid', 'cpu' and 'set'.
