Subject: [PATCH 0/2] perf kvm: Fix memory leak

This patch seris is to address memory leak issues in perf kvm.

The first patch introduces refcnt in structure kvm_info, so we can avoid
memory leak for it.

The second patch explicitly delete histograms entries before program
exiting rather than relying on kernel releasing memory space.


Leo Yan (2):
  perf kvm: Support refcnt in structure kvm_info
  perf kvm: Delete histograms entries before exiting
