perf machine: Fix to destroy kernel maps when machine exits
Actually machine__exit forgot to call machine__destroy_kernel_maps. This fixes some memory leaks on map as below. Without this fix. ---- ./perf probe vfs_read Added new event: probe:vfs_read (on vfs_read) You can now use it in all perf tools, such as: perf record -e probe:vfs_read -aR sleep 1 REFCNT: BUG: Unreclaimed objects found. REFCNT: Total 4 objects are not reclaimed. To see all backtraces, rerun with -v option ---- With this fix. ---- ./perf probe vfs_read Added new event: probe:vfs_read (on vfs_read) You can now use it in all perf tools, such as: perf record -e probe:vfs_read -aR sleep 1 REFCNT: BUG: Unreclaimed objects found.
