As noted in your cover letter:

 * A fix for a memory leak in the Trace2 code. (This was independently
   reported in last week in "ab/tr2-leaks-and-fixes".)

So I think this patch can be dropped from this series, since it's exact
duplicate of my 48f68715b14 (tr2: stop leaking "thread_name" memory,
2021-08-27) in ab/tr2-leaks-and-fixes, currently in "next" and marked
for a merge with master.

When submitting a series that depends on another one it's best to rebase
it on top of it & indicate it as such in the cover letter, Junio can
queue such a series on top of another one.

In this case I'm still not sure why this fix is here, i.e. surely
nothing later in the series absolutely needs this stray memory leak
fix...
