Subject: [PATCH v6 10/15] perf c2c: Rename dimension from 'percent_hitm' to 'percent_costly_snoop'
Date:   Thu, 11 Aug 2022 14:24:46 +0800
Message-Id: <20220811062451.435810-11-leo.yan@linaro.org>
In-Reply-To: <20220811062451.435810-1-leo.yan@linaro.org>

Precedence: bulk

Use more general naming for the main sort dimension, this can allow us
not to sort only on HITM snoop type, so it can be extended to support
other costly snooping operations.  So rename the dimension to the prefix
'percent_costly_".
