[PATCH 0/1] perf test: Fix attr tests for PERF_FORMAT_LOST

[James Clark]

I'm not sure what the rule is for backwards compatibility of tests, but
in this case my change will not work on older kernels because I replaced
the previous expected value, rather than adding it as another valid one
with an OR. Like "read_format=4|20"

To me it seems that running the tests is a different workflow than say
someone running Perf itself on older kernels. And if we keep adding to
the valid values in tests, then the tests become less useful over time.

PERF_FORMAT_LOST is not an optional feature so it _should_ always be
present. For that reason I chose to not add it as an extra valid value,
but I'm happy to change it if we think that new tests should also pass
on older kernels.

Thanks
James
