[RFC 1/8] test/ring: avoid shadow variable usage

Stephen Hemminger stephen at networkplumber.org
Thu Aug 28 01:14:04 CEST 2025


The code had a global array "esize" and also local variable
with same name. This would cause warnings if -Wshadow was enabled.
Fix by renaming the array to "esizes".

Fixes: a9fe152363e2 ("test/ring: add custom element size functional tests")
