Subject: perf test: Use machine__new_host in mmap thread lookup test
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=046847935754f27c2e8334ff15abda0b733a1fd4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

perf test: Use machine__new_host in mmap thread lookup test

This is more straightforward than what we have now.

It also fixes a segfault within machine__exit, that's caused by 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
