Subject: [PATCH v4 0/2] perf kvm stat live: Copy events


This is a fix of 'perf kvm stat live' crash when it tries
to parse events that have been already overwritten by the kernel.

- 1/2 adds an option to copy events when they are pushed to the samples queue.  The patch is based on the patch by David Ahern (
- 2/2 enables the copying for perf kvm stat live.

Changes in v4:
  - removed extra whitespaces :)

Changes in v3:
  - move repetitive code into functions

Changes in v2:
  - the option to copy events is now a part of ordered_events
  - use memdup() instead malloc()/memcpy()
  - events alocations are under the report.queue-size limit
