Actually machine__exit forgot to call machine__destroy_kernel_maps.
So this fixes to call it. 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
