Errors from create_gcov are also set to be ignored. This is because some

failing the create_gcov command. This is expected and is not an error
condition.
This seems fairly drastic. It will probably hide a lot of other
problems risking unnoticed regressions.
Yeah, I feel the same way. This was just the first (and easiest) solution I
came up with. I couldn't really think of a better way to do this, though ...
Perhaps better check explicitly like you did in your exaqmple.
... this sounds much better and didn't cross my mind. I will try this.
For example:
perf buildid-list -i prev-libbacktrace/perf.data
aff9c7b2c5c294612904563fa3da88cb054d313d [kernel.kallsyms]
