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

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

Patches
- 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 (https://lkml.org/lkml/2013/9/6/388)
- 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

Alexander Yarygin (2):
perf tools: Add option to copy events when queueing
