Subject: [PATCH] perf auxtrace: Fix queue resize
Date: Tue, 14 Aug 2018 11:46:08 +0300 [thread overview]
Message-ID: <20180814084608.6563-1-adrian.hunter@intel.com> (raw)
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'.
Fixes: e502789302a6e ("perf auxtrace: Add helpers for queuing AUX area tracing data")
