For 5.10, yes, but probably we need to send this to stable@ since Thomas
reported it failing on v5.9.

Does a55b7bb1c146 have a Fixes: tag?

Yes!

[acme@...e perf]$ git show a55b7bb1c146 | grep Fixes:
    Fixes: commit f5a56570a3f2 ("perf test: Fix memory leaks in parse-metric test")
[acme@...e perf]$ git tag --contains f5a56570a3f2 | grep ^v | head -1
v5.9
[acme@...e perf]$

So v5.9.1 will probably get this automagically cherry-picked.

Good.
