bug#53351: [PATCH] gnu: Add flamegraph.

[Mathieu Othacehe]

Hello Olivier,

Something went wrong with the patch export format as the commit message
appears as a separate MIME part here. Did you use "git send-email"?

> +    (version "1.0")

I modified the version to: 1.0-1.810687f so that it takes the selected
commit into account.

Pushed as 410211c42388f99c22a7b4140553be35e696400e.

Thanks,

Mathieu

Yes as I always I use git-send-email.  Weird.
