Subject: [PATCH 0/2] perf kvm: Fix memory leak
Date: Mon, 20 Mar 2023 14:16:17 +0800	[thread overview]
Message-ID: <20230320061619.29520-1-leo.yan@linaro.org> (raw)

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.

  perf kvm: Support refcnt in structure kvm_info
  perf kvm: Delete histograms entries before exiting
