> Subject: [PATCH] app/compress-perf: prevent output buffer overflow
> 
> This patch fixes the issue of memory overwrite after the end of
> the output buffer by calculating its size as the number of all
> segments multipled by the output segment size.
> Additionally buffer overflow errors returned by PMD driver are
> detected and shown, ending the test.
> 
> Also the output buffer size multiplier was increased from 105%
> to 110% to allow running the tests on noncompressible files that
> expand to over 107% of original size during the compression.
> 
> The changes were made in the verification part of the flow and
> they don't affect the benchmark results.

> Fixes: 424dd6c8c1 ("app/compress-perf: add weak functions for multicore test")
