[PATCH] perf test: Do not compare overheads in the zstd comp test
From: Namhyung Kim
Date: Thu Aug 12 2021 - 19:57:47 EST
The overhead can vary on each run so it'd make the test failed
sometimes. Also order of hist entry can change.
Use perf report -F option to omit the overhead field and sort the
result alphabetically.
