[PATCH 7/7] perf test: Create kernel maps properly for hist entries test

Show all headers | View raw

It fixes segfault within machine__exit, that's caused
but not creating kernel maps for machine.. We're calling
machine__destroy_kernel_maps in machine__exit since commit:

  ebe9729c8c31 perf machine: Fix to destroy kernel maps when machine exits
