I noticed that the current upstream Linux tree doesn't contain a
`tools/drgn/` directory.

I'm interested in contributing a drgn script tool as well.
Given that this directory does not yet exist in mainline, where would
be the appropriate place to add new drgn scripts? Would it make sense
to create a new `tools/drgn/` directory, or is there a preferred
location for such debugging scripts?

Thanks,
Ye
