From 300ec47ab8ea3434ed4b7e7cb5e8eeccc5ad9def 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'.
